Braintree Police identified the suspect in this as Charles N. Diorio, 49, of Chelsea.
Diorio is being charged with armed assault in a dwelling, kidnapping, witness intimidation, threats to commit a crime, illegal possession of a firearm, giving a false name to police after arrest and being a fugitive from justice.
According to Braintree Deputy Police Chief Russell Jenkins, the suspect had a parole violation warrant out of California. The warrant details are not known, he said.
"I cannot confirm what the violation is and I cannot confirm that he is a sex offender," Jenkins said. "New York is unable to confirm any warrant with them."
Braintree Police did confirm that Chelsea Police were looking for Diorio for his involvement with an assault with a firearm.
Jenkins described the situation that unfolded early Sunday.
"A 46-year old Braintree woman came to the Braintree Police station at approximately 5:00 a.m. Sunday morning to report that Diorio, who she had a prior relationship with and knew by another name, forced his way into her apartment at approximately 1:00 a.m. and held her there against her will," the deputy chief said.
Diorio took the woman's licensed firearm when he got inside the apartment, he said.
"Concerned that a friend of the woman would be arriving at approximately 4:00 a.m., Diorio threatened to kill the friend if she did not call him and tell him not to come over," Jenkins said.
However, the victim's friend did come to the apartment before 5:00 a.m. and the two managed to exit the apartment and drove to the police station.
Police responded to the scene along with a SWAT team. The Metropolitan Law Enforcement SWAT Team assisted the Braintree Police with taking Diorio into custody.
"After establishing a secure perimeter and evacuating other residents of the apartment building, crisis negotiators called Diorio and ultimately convinced him to surrender," Jenkins said.
The suspect was arrested at 9:15 a.m. Sunday without incident.
Detectives were on the scene all morning and afternoon, collecting evidence. K-9 Units from the Quincy Police Department and the Plymouth County Sheriff's Department also assisted BPD on the scene.
Police "recovered the woman’s firearm with a loaded magazine and several loose rounds of ammunition," Jenkins said. "The woman told investigators that she did not own any ammunition for the weapon and police now theorize that the weapon used in the Chelsea incident may in fact be the woman’s handgun that was taken without her knowledge and brought back by Diorio that morning."
Police said the investigation is ongoing.
