A three-hour standoff between Newton police and a knife-wielding 23-year-old man ended peacefully Thursday after police managed to disarm the man, according to a Newton police spokesman.

Police responded to calls about a disturbance at a home on Mechanic Street just before 2 p.m., said Newton Police Lieutenant Bruce Apotheker, and arrived to find the man standing on his front stoop next to his mother. He was holding a knife and threatening to harm himself, Apotheker said.

Police began speaking with him, Apotheker said, and Northeastern Massachusetts Law Enforcement Council SWAT team officers assisted.

While Apotheker said it was not clear if the man was threatening to hurt others, his refusal to drop the knife worried police. Police evacuated two or three homes, he said, and shut down the street, though there were enough officers there that officials were not concerned about the safety of other residents.


At around 5 p.m., Apotheker said, police were able to approach the man, who was still holding the knife, and disarm him.

“The situation resolved itself peacefully,” Apotheker said.

The man, whom authorities have not identified, was taken to Newton-Wellesley Hospital. He has not been charged, though Apotheker said the incident remained under investigation.
