LOWELL -- A 35-year-old Lowell man was arrested with help from a North Eastern Massachusetts Law Enforcement Council SWAT team after he allegedly assaulted a family member with a knife Monday and then threatened to stab anyone, including police, who entered his home.

Police were called to 418 Westford St. at the intersection with Wilder Street about 6 p.m. after a 911 caller alleged Tien To, 35, of 418 Wilder St., threatened them with a knife, trashed the apartment, and threatened to stab anyone who entered the home.

To refused to leave the home when police arrived, according to police. To's family members had already fled the home.

Since To was armed, alone inside the home, and refused to open the door, police surrounded the home and requested help from a NEMLEC SWAT team, with officers trained at getting suspects to surrender without using violence.

Officers spoke to the suspect via a bullhorn when To stepped out on a second floor balcony. Officers told To his family was concerned about him and asked him to surrender.

A short time later To surrendered without incident.

He was charged with domestic assault with a dangerous weapon (knife), domestic assault and battery and malicious destruction of property. He was scheduled to be arraigned Tuesday in Lowell District Court.

To previously served prison time for larceny, and was arrested in 2012 for allegedly assaulting a police officer.
