Eddie Chrispin, a spokesman for the Boston Police Department, said that police came to Parvaiz's address on Waldemar Street, East Boston, in late February of this year in response to a domestic violence incident involving a 20-year-old woman.
"The victim alleged the suspect had assaulted her. The suspect was placed under arrest," he said.
That woman, who was from Brooklyn where Parvaiz grew up, was neither Stephen nor Noorani, said Jake Wark, a spokesman for the Suffolk County district attorney in Boston.
After Parvaiz's arrest on the domestic-violence rap, the alleged victim said that she didn't want to take part in the prosecution, but the DA sent her a summons anyway, Wark said.
"She did not appear at the trial date" on May 1, Wark said, so the case was dismissed.
The Boston incident was triggered by Parvaiz accusing the 20-year-old of being unfaithful to him, authorities said.
Parvaiz, who ran a construction business, Riyaan Developers, which is listed as operating in his East Boston home and in Brooklyn, where his family lives, had told relatives that he was a graduate student at Harvard University. But a Harvard spokesman said the university has not found a record of his enrollment.
