An assistant basketball coach at Wake Forest University was arrested on Thursday in New York City after a man whom the police say he punched in Queens over the weekend died of his injuries.

The victim, Sandor Szabo, 35, of Florida, fell onto the pavement and lost consciousness after he was punched in the face during a confrontation just after 1 a.m. Sunday in Long Island City, the police said. After Mr. Szabo fell, security footage showed his attacker walking away, and the police said he left the scene in a white sport utility vehicle. Mr. Szabo was taken to a hospital in critical condition. He died on Tuesday afternoon.

The Associated Press, citing a person familiar with the investigation, reported that Mr. Szabo might have been banging on car windows just before the confrontation.

The man who was arrested, Jamill Jones, 35, who lives Kernersville, N.C., turned himself in on Thursday to face a charge of misdemeanor assault. Mr. Jones pleaded not guilty and was released on his own recognizance, said Alain Massena, his lawyer.
