HOPKINTON — Police took a 69-year-old Walcott Street man into custody Wednesday afternoon following a two-hour standoff that ended without incident.

Family members called police around 12:15 p.m. to report their father had gone into a small out-building on the property following a violent argument. Those family members told police the man had access to guns and they were worried for his well-being, according to a press release from Hopkinton Police.

Several nearby homes were evacuated as the fire department ambulance and support vehicles were dispatched.

The man refused several requests to surrender, police said.

A member of the Hopkinton Police Department, active in the Central Massachusetts Law Enforcement Council S.W.A.T. team, was participating in group training session. The team was sent to Walcott Street.

Police made several unsuccessful attempts to negotiate by phone. Hostage negotiators then deployed a vehicle-mounted public address system to provide one-way communication with the man. He surrendered at 2:34 p.m. and was taken to a hospital for evaluation.

He was charged with domestic assault and battery and possession of a sawed-off shotgun. He will be arraigned when he is discharged from the hospital, police said.

Police said the "cooperation and patience" of the neighborhood residents was critical in ensuring a "safe scene" for police in which to work. Police said the staff and resources of the Central Massachusetts Swat Team and the Worcester County Sheriff's Office were instrumental in the incident.
