On Monday, police nabbed another biker in connection with the brawl. Craig Wright, 29, of Brooklyn, was arrested on charges of gang assault, assault and unlawful imprisonment, police said. It wasn’t clear if he had a lawyer. A telephone call to his home was not answered.
Three other bikers have been charged so far, and police continue to investigate. Lien has not been charged.
The detective was off-duty when he joined the Sept. 29 rally, Karasyk said. While off-duty officers are expected to act if they see a crime, undercover officers do so only in rare circumstances.
Karasyk said the detective, who had no gun or badge with him, was conscious of cases where officers blew cover only to be suspended or dismissed for doing so.
“He had no other option, so he drove away,” he said.
The detective did not report his presence there until three days later. Chief police spokesman John McCarthy said the officer was stripped of his gun and badge while internal affairs investigates the delay.
