A retired police lieutenant fatally shot himself inside the Bloomfield Police Department in New Jersey after he was arrested over a domestic violence incident.

According to NBC News, 58-year-old Patrick Montella was in the process of being released when he lunged for his old service weapon—which had been collected during his arrest— and shot himself.

The retired officer was transported to a nearby hospital, where he was pronounced dead.

Montella had served with the Newark (NJ) Police Department.

The president of the Newark Police FOP Lodge 12 said the incident "has shaken the Newark Police Department to its core."
