Former Lawrence Police Captain Charged with Civil Rights Violations and Submitting False Reports

BOSTON – A former Lawrence Police Captain was arrested and charged in connection with an alleged assault on a man in Lawrence Police custody.  

Michael M. Mangan, 47, of Derry, N.H., was indicted by a federal grand jury with one count of deprivation of rights under color of law and two counts of false reports. The defendant was arrested on Oct. 29, 2025 and was released on conditions following an initial appearance in federal court in Boston.

According to the indictment, on March 10, 2023, while on duty as a Captain with the Lawrence Police Department, Mangan assaulted a person who had been arrested, resulting in bodily injury the victim. The indictment further alleges that Mangan submitted two false reports about the incident, including a report in which he falsely stated that during the booking process, the victim “slightly turned and bladed his body towards” Mangan “and simultaneously threw his right arm and outstretched hand at a high rate of speed towards [Mangan’s] face with his fingers in a grabbing motion. It alleged that he also stated that the victim demonstrated “assaultive action,” that there was an “imminent threat of the victim reaching to grab at [Mangan’s] face” and that he “utilized a straight arm take down” with his right arm across the victim’s chest. As alleged in the indictment, Mangan submitted these false reports intending to impede, obstruct or influence an ensuing federal investigation.

The charge of deprivation of rights under color of law provides for a sentence of up to 10 years in prison, up to three years of supervised release and a fine of up to $250,000. The charge of false reports provides for a sentence of up to 20 years in prison, up to three years of supervised release and a fine of up to $250,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.

United States Attorney Leah B. Foley and Ted E. Docks, Special Agent in Charge of the Federal Bureau of Investigation made the announcement. Assistant U.S. Attorneys Kristina E. Barclay and Brian A. Fogerty of the Criminal Division are prosecuting the case.

The details contained in the charging document are allegations. The defendant is presumed to be innocent unless and until proven guilty beyond a reasonable doubt in the court of law.
