Self-Appointed Security: Lewiston Activist’s Confrontations Raise Questions About Who She Is Really Protecting

Melissa Dunn has spent years presenting herself as a peace activist, tenant advocate and community organizer in Lewiston.

But her increasingly visible role at political events, outside a Lewiston Mosque and during confrontations with reporters, residents and law enforcement has raised questions about whether Dunn’s activism is reducing tensions in Maine’s second-largest city, or contributing to them.

Those concerns intensified last Friday when the Lewiston Police Department brought additional officers into the Bartlett Street area amid concerns about potential trouble between Dunn’s self-described safety team and members of the general public, according to information provided to The Maine Wire.

The deployment raises questions about why an already short-staffed police department is being required to devote additional personnel to managing tensions surrounding an unofficial private security group.

Is Dunn helping keep the peace, or are her tactics creating conditions that require police intervention?

That question carries broader consequences for a city already struggling with a wave of youth-involved shootings and increasing scrutiny from national media outlets.

Lewiston’s reputation has suffered as violence, political dysfunction and public confrontations have repeatedly placed the city in the headlines. Once known as a proud industrial community built by generations of working families, Lewiston is now increasingly portrayed to the rest of the country through images of shootings, disorder and division.

Against that backdrop, the spectacle of a self-appointed safety committee confronting residents and requiring additional police resources raises another unavoidable question: Is Dunn helping restore confidence in the city, or further damaging the image of a once-great community already fighting to overcome years of negative attention?

Dunn has been active in Lewiston for more than a decade, previously working in tenant advocacy and neighborhood organizing. Earlier news reports identified her as a downtown resident and community organizer involved in demonstrations opposing racism and violence.

News Center Maine identified Dunn in 2016 as one of the organizers of the Visible Community’s “I Love My Blackness and Yours Freedom Rally.” In 2019, she spoke publicly following a deadly street fight in Lewiston and argued that racial tensions had contributed to violence in the city.

More recently, however, Dunn’s activism has expanded beyond organizing rallies and addressing elected officials.

She reportedly provided security at multiple events for Graham Platner’s former U.S. Senate campaign.

Publicly available campaign records do not clearly establish whether Dunn was a paid campaign employee, contractor or volunteer. Her precise title and financial relationship with the campaign, if any, remain unclear.

Dunn has also become a central figure in a group known locally as the “safety squadron,” “safety brigade” or mosque safety committee. The group has gathered on Fridays near a mosque and the offices of Maine Immigrant and Refugee Services on Bartlett Street.

Supporters describe the operation as an effort to protect worshippers from harassment and monitor activity near the mosque.

Critics, however, contend the group has contributed to an increasingly confrontational atmosphere involving worshippers, neighboring businesses, pedestrians, reporters and members of the public.

Dunn does not appear to be an employee of the mosque, a religious official, a licensed law enforcement officer or a publicly identified professional security guard. No publicly available record reviewed by The Maine Wire establishes that the mosque has formally appointed her to oversee security.

Her role instead appears to be that of an outside activist participating in or directing an informal security operation.

That distinction matters because Dunn’s team has reportedly attempted to monitor vehicles, question individuals and control activity around public sidewalks and privately owned parking areas without the authority or accountability normally attached to law enforcement or licensed security personnel.

The long-running dispute has already consumed police time and city resources.

In May, Matthew Theriault of Mid Valley Motors Towing and Recovery filed a request for protection from harassment against Dunn amid a dispute over parking areas near the mosque and Maine Immigrant and Refugee Services.

Theriault alleged that Dunn refused to accept the order when police attempted to serve it. The filing represented allegations and did not, by itself, establish that Dunn committed a crime or that the accusations were proven in court.

The Maine Wire has also reported that Dunn followed a Homeland Security Investigations agent through Lewiston after apparently mistaking the agent for an Immigration and Customs Enforcement officer.

The agent was reportedly conducting unrelated duties at the time.

No publicly available criminal conviction connected to that reported encounter has been identified. Nevertheless, the incident raised concerns about private activists following government agents based on their assumptions about what those agents might be doing.

Dunn has also had a physical confrontation with a Maine Wire reporter.

Video recorded inside Lewiston City Hall appears to show Dunn making physical contact with and pushing reporter Jon Fetherston during a City Council meeting. Police subsequently directed Dunn to leave the building.

Police Resources Diverted as Department Faces Shortage

The latest concerns extend beyond Dunn’s conduct and into the allocation of limited Lewiston police resources.

The department assigned additional officers to the Bartlett Street area last Friday to prevent potential confrontations between Dunn’s safety committee and members of the public.

It remains unclear how many additional officers were deployed, how long they remained in the area or what the operation cost taxpayers in salaries, overtime or diverted patrol coverage.

The additional police presence comes as the Lewiston Police Department continues attempting to fill vacant positions.

Lewiston officials have acknowledged staffing difficulties for years. In 2024, the department reportedly had 79 officers, seven below its authorized staffing level. In August 2025, the department was reportedly down nine officers, or approximately 12 when personnel on medical leave were included.

The department continues actively recruiting officers and advertises that it handles more than 53,000 calls for service annually.

More recent information presented to the City Council indicated that the department was down approximately 11 officers, or 12 when an injured officer was included.

Against that backdrop, every additional deployment has consequences.

Officers assigned to monitor an unofficial safety committee are officers who may not be available for routine patrols, traffic enforcement, community policing or the city’s continuing response to shootings and juvenile violence.

That tradeoff is particularly concerning in a city where young people have been repeatedly connected to shootings, stolen firearms and other serious crimes.

Lewiston police, schools and community organizations are already under pressure to address youth violence and restore a sense of safety. Diverting officers to prevent confrontations involving a private activist group risks pulling resources away from the very neighborhoods and young people facing the city’s most urgent public-safety problems.

The central question is not whether police should respond when there is a credible threat of trouble. Preventing violence is a core police responsibility.

The question is why a private activist group’s presence appears to be creating circumstances in which the city believes additional police staffing may be necessary.

If the committee genuinely makes the neighborhood safer, why does its presence require additional police officers to prevent conflict?

If the operation repeatedly produces confrontations, complaints and police responses, city leaders should determine whether it is functioning as a safety initiative or becoming another source of disorder.

Silence From City Hall

Lewiston Mayor Carl Sheline and members of the City Council have said little publicly about Dunn’s unofficial security operation, the strain it may place on police personnel or the potential cost to taxpayers.

No detailed public accounting has been released showing how many calls for service, officer hours or overtime expenses have resulted from the continuing Bartlett Street disputes.

City officials have also not publicly explained whether Dunn’s group has any recognized relationship with the city, the mosque or local law enforcement.

The silence is especially notable given the City Council’s responsibility for overseeing municipal spending and evaluating how limited police resources are used.

Councilors regularly debate comparatively minor spending requests, staffing allocations and departmental expenditures. Yet an unofficial group whose activities have repeatedly drawn police attention has received little visible scrutiny from elected officials.

That leaves Lewiston residents with several unanswered questions.

How many times have police been called because of disputes involving Dunn or members of the safety committee?

How many officer hours have been spent monitoring the group?

Has the city incurred overtime expenses?

Did the police department specifically request that Dunn’s team stop or modify any of its activities?

Does the mosque formally authorize Dunn to act on its behalf?

Has the mayor met with Dunn, mosque leaders, neighboring business owners or police officials about the situation?

As the above photo shows, Mayor Sheline was seen entering the mosque on Friday. It was also reported by online influencers that they met with the Mayor,as well.

Who alerted these online influencers to the issues in Lewiston?

And why have the mayor and City Council not publicly addressed the use of city resources?

The lack of public leadership also carries reputational costs.

National media outlets have increasingly turned their attention toward Lewiston as the city deals with shootings, crime, political disputes and confrontational activism. Every new incident reinforces a public image that city leaders should be working aggressively to change.

If elected officials remain silent while an unofficial security operation contributes to police deployments and public confrontations, they risk allowing outside audiences to conclude that Lewiston is unable or unwilling to maintain order through its established institutions.

Public safety decisions should not be made through silence, informal arrangements or deference to politically connected activists.

If Dunn’s committee is providing a legitimate and valuable service, city officials should explain its function, authority and relationship with the police.

Dunn has also used social media to publicly criticize several of Lewiston’s most prominent officials and institutions, including Mayor Carl Sheline, Androscoggin County District Attorney Neil McLean and the Lewiston Police Department. Her comments have questioned the judgment, priorities and performance of local leaders and law enforcement, further establishing her as an outspoken—and frequently confrontational—presence in city politics. While residents have every right to challenge public officials, Dunn’s repeated attacks raise questions about whether she is seeking constructive accountability or deepening public distrust in the same institutions now being called upon to manage tensions surrounding her unofficial safety group.

If the group is increasing tension and forcing an understaffed department to devote extra officers to preventing confrontations, residents deserve to know that as well.

Peacekeeper or Source of Escalation?

Dunn’s supporters may see a committed organizer willing to defend immigrant residents, mosque attendees and other vulnerable communities.

Her critics see a self-appointed enforcer who monitors strangers, follows suspected federal agents, confronts journalists and inserts herself into disputes without any publicly established legal authority.

There is no evidence that Dunn is literally attempting to begin a civil war.

But that does not make questions about her tactics illegitimate.

A peacekeeper reduces conflict. A peacekeeper calms volatile situations, respects lawful boundaries and helps police avoid unnecessary confrontations.

An activist whose presence repeatedly generates complaints, legal filings, physical confrontations and additional police deployments may be producing the opposite result—regardless of her stated intentions.

Lewiston does not need more division.

It needs fewer shootings, stronger neighborhoods, restored confidence in law enforcement and elected officials willing to defend the city’s reputation.

Dunn says she is protecting the community.

Lewiston’s elected officials must now explain whether her activities are actually making the city safer, whether they are increasing tensions, and whether taxpayers are being asked to fund the police response to problems her unofficial security operation is helping create.

For a city already fighting to repair its image before a national audience, the answer matters far beyond Bartlett Street.
