NEW HAVEN, Conn. (WTNH) – A man is in police custody after barricading himself inside a home on Winthrop Avenue on Monday night, according to authorities.

New Haven police said Winthrop Avenue was closed between Maple Street and Elm Street for several hours because of a barricade involving a man who appeared to be having a mental health issue. Police asked the public to avoid the area.

Police responded to the home on Winthrop Avenue after receiving a report from a business asking for the person not to trespass on their property as he had just been let go from work.

Officers said the man became upset and agitated while speaking with police. Police said the man went back inside the home and barricaded themselves inside.

A special weapons and tactics team (SWAT) and hostage negotiators responded to the scene.

The person is known to the department and has mental health issues, police said.

Police announced that the barricade ended around 9:30 p.m. when the man exited the home without further incident.

“The person is known to us he has mental health issues he wouldn’t let the police in and started having some problems, mental health problems. He stayed within the house, but there is a possibility there are firearms in the house. Negotiators are able to talk to him and with the help of the family he came out of the house,” New Haven Police Chief Karl Jacobson said.

The New Haven Police Department has added ten new negotiators to the team, which is helpful for people who are in the midst of mental health crises.
