PORTSMOUTH — A domestic assault led to a SWAT team response to a city neighborhood early Sunday morning, when a resident threatening "suicide by cop" was arrested on two charges, police said.

George Rinalducci, 70, of 244 Austin St., assaulted a woman, then attempted to call her by cell phone while she was being treated for "minor injuries" at Portsmouth Regional Hospital, the police said in a prepared statement. When officers arrived at his home, he had left the area in spite of instructions by officer Steven Blanding to turn himself in, police said.

Instead, Rinalducci told the officer that if police attempted to take him into custody, they "would have to shoot him," according to police. In the meantime, police say it was learned that Rinalducci is a gun collector and "avid marksman."

Online records show Rinalducci is a member of the Piscataqua Fish and Game club, which has shooting ranges, as well as a principal of "Deuce & Sons Firearms" run out of his home.

After Rinalducci is believed to have gone to Dover, his car was located at a friend's Portsmouth home, where he was inside with the friend's elderly mother, police said. "Given the nature of the threats" he made, the Seacoast Emergency Response Team was activated and officers from State Police, Greenland and Newington were called to assist with Rinalducci's capture at about 3:20 a.m., police said.

Rinalducci is charged with violating a protective order and simple assault. He is scheduled to be arraigned today in the Portsmouth Circuit Court, according to police.
