Brunswick Officer Day Faces Federal Suit Over 2025 Traffic Stop
Plaintiff alleges officer slammed teen's head into car, knocking her out, while town officials claim discipline was insufficient.
By Sofia Ramirez ·
A federal lawsuit filed Friday seeks compensation for a woman who alleges a Brunswick police officer knocked her unconscious during a traffic stop last December.
The complaint names Officer Nathan Day, 27, an unnamed officer, and the Town of Brunswick. It states that Day used excessive force against the then-17-year-old, slamming her head into her vehicle and the ground. The filing claims this action left her with severe injuries and that she was falsely arrested without probable cause.
Day was charged with Class D assault in March. He waived his arraignment and has pleaded not guilty to the misdemeanor. Chief Scott Stewart confirmed that Day was placed on administrative leave one day after the incident on Dec. 18, 2025. Stewart said he had not heard of the lawsuit when contacted for comment.
The suit describes the events at the Cook’s Corner shopping plaza. Officers stopped the teen’s boyfriend for a traffic violation while he waited for a taillight repair. She followed him into the lot in a separate car. According to the filing, Day ordered her out of her vehicle while she waited across the parking lot and then assaulted her, rendering her unconscious.
The plaintiff suffered a head wound requiring staples, a concussion, and foot fractures. The lawsuit also alleges she experienced seizures. She was transported to the hospital in handcuffs. The traffic violations used to justify her arrest were dismissed in September.
Marc Beaudoin, Day’s attorney, disputed the account in an email on Friday. He said Day asked the teen to approach him to issue a ticket for using her cellphone while driving. Beaudoin stated that when she refused, Day moved to handcuff her and she kicked his knee. He argued the injuries were inadvertent and resulted from her refusal to comply, not from excessive force.
The complaint cites department records showing Day received formal discipline three times before the alleged assault. These incidents occurred in September 2023, July 2025, and August 2025. The August 2025 report involved a tackle of a suspect, which required remedial training. The other two reports concerned policy violations while driving a police cruiser.
Attorneys for the plaintiff said the case addresses the town's failure to discipline Day for what they called escalating misconduct. They accused the department of deliberate indifference to reports of officer behavior. The plaintiff is seeking compensatory and punitive damages, plus attorney’s fees, and has requested a jury trial.
