NEWARK -- A New Jersey hockey fan is suing the Prudential Center, the city of Newark, and a handful of others, claiming he has had to undergo thousands of dollars worth of plastic surgery after being beaten up outside the arena.

John Malley has filed a civil suit stemming from an alleged altercation after a Dec. 23, 2014 Devils' game. According to the suit, Malley was leaving the Prudential Center with two friends when one of them got into a verbal fight with two fellow game attendees, a father and son from Oak Ridge.

It is unclear what prompted the fight, but Malley's attorney, Brian Schiller, said it turned physical in the arena's parking deck after Malley's friend threw a slice of pizza at one of the men.

When Malley tried to intervene, one of the men "picked John up, body slammed him backwards onto the ground, struck him in the face several times with a closed fist and then kicked him in the face...(and later) delivered the final knockout punch," Schiller said.

According to the filing, Malley suffered serious injuries, including several fractured facial bones, blocked nasal passages in both nostrils, a concussion, and a deviated septum.

After a police investigation, which the suit claims included a video of the altercation, the father and son were not charged criminally in connection to the incident, Schiller said. Malley's suit claims the arena, its security, and the city were negligent in preventing and responding to the fight.

Spokespeople for the city and the Newark police department did not return requests for comment on the suit and investigation into the fight.

A spokesman for the Prudential Center declined to comment on the suit. The father and son allegedly involved in the fight, who are also named as defendants in the filing, could not be reached for comment.

Schiller declined to release the video of the altercation, saying juveniles are in the video. He also said Malley is seeking an unspecified sum in damages tied to his medical bills and "emotional trauma" stemming from the incident.
