FALL RIVER, Mass. (WPRI) — An investigation is underway after a man was shot and killed during an altercation with police in Fall River Monday evening.

Bristol County District Attorney Thomas Quinn said the incident occurred inside a first-floor apartment on Melville Street.

Officers initially responded to a home on Lowell Street for reports of a past domestic incident, according to Quinn.

Quinn said the victim, identified only as a woman, told the officers Anthony Harden, 30, had assaulted her on Saturday afternoon while she was inside a Melville Street apartment.

After speaking with the victim, Quinn said the officers went to the apartment to speak with Harden.

Quinn said after the officers spoke with Harden, an altercation ensued.

During that altercation, Quinn said one of the officers shot Harden. Harden was rushed to St. Anne’s Hospital where he was later pronounced dead.

Quinn noted that it appeared Harden had a knife on him at the time of the incident, but did not specify whether he threatened the officers with it.

Per department protocol, Quinn said both officers were also transported to the hospital to be evaluated. It’s unclear if either were injured in the incident, or if they’ve been placed on leave.

The investigation into the incident remains ongoing.
