A Brunswick police officer is accused of assaulting a minor in December, according to court documents and an attorney who says he’s representing the girl.

Nathan Day, 26, of Gardiner, was charged with Class D assault Monday. According to a complaint filed in West Bath District Court, the alleged misdemeanor assault occurred on Dec. 18, one day before Day was placed on administrative leave.

Brunswick police Chief Scott Stewart confirmed that Day is still on administrative leave but declined to comment on the charge, calling it an active personnel issue.

Additional court documents that would describe the nature of the assault weren’t available Wednesday. Efforts to reach Day were unsuccessful.

Andrew Wright, a Brunswick-based attorney, said he is representing the victim, whom he described as a girl still dealing with medical issues after being assaulted in December.

Wright said he’s grateful that the Office of the Maine Attorney General brought the charges against Day, adding that “there is no place in Maine for this type of violence against our children.”

“Mr. Day deserves to have significant consequences for his actions and will hopefully never be in a position where he can harm our citizens again, especially children,” Wright said in a written statement Wednesday. “Police officers like Mr. Day should never taint the reputation of good law enforcement officers and absolutely should never terrorize and harm our children.”

A spokesperson for the attorney general’s office did not immediately respond to questions Wednesday about the circumstances of the alleged assault.

Day has worked at the police department since May 2022, according to records from the Maine Public Employee Retirement System. He previously worked for the town of Brunswick as a Public Works truck driver from March 2020 until he was hired at the police department, Town Clerk Fran Smith said.

Stewart said when an officer is placed on administrative leave, the department conducts an internal affairs investigation focused on department policy.
