NEW BRUNSWICK — A YouTube video shows four New Brunswick police officers holding a Rutgers University student face down in the street as one punches him.

"Give me your hand. Stop resisting," officers are heard yelling just before one punches the student four times.

The student was one of two arrested at a street brawl outside a college house party.

City Police Director Peter Mangarella officers are reviewing the YouTube video as well as those from cameras in police cruisers parked nearby.

After seeing the YouTube images, Mangarella said "the guy was still actively resisting arrest while on the ground."

He said the department is examining whether correct procedures were followed. All officers involved remain on active duty, and not one has been reassigned, he said.

At 12:50 a.m. Saturday, police went to a fight in the road at Stone and Prosper streets, where they arrested two students, Elliot Marx, 20, of Lindenhurst, N.Y. and Joseph Keepers, 21, of Edison, said Lt. J.T. Miller.

He said about 50 people were in the street when officers arrived, and when one officer tackled Keepers to stop him from kicking another person, Marx jumped on the officers’s back.

The video, taken by somebody apparently in a nearby house, begins after officers wrestled Marx to the ground.

Marx was charged with resisting arrest, aggravated assault on a police officer, obstructing police and having a fake identification.

When reached today, Marx said he and Keepers tried to enter a house party on Stone Street, but somebody at the door punched him in the face and a fight ensued. During the brawl, he saw Keepers being tackled and tried to help his friend, he said.

"I didn’t even know it was police. I had no idea they were police until they said stop resisting," said Marx, a junior at the university school of Arts and Sciences.

He was taken to the Middlesex County jail and treated for bruises and cuts on his face. After he was released on $10,000 bail, friends informed him of the video, he said.

Keepers, a senior majoring in psychology, was charged with disorderly conduct and released, pending a court hearing. Attempts to reach him were unsuccessful.

Jon Shane, from the Department of Law and Police Science at John Jay College in New York City, said the YouTube video showed officers acting appropriately.

"The amount of force looks reasonable," said Shane, a retired Newark police captain. While the student is on the ground, "he's not in custody. Who knows what he's doing or saying down there," said Shane. He said officers didn't know if the student had a weapon under him. "You're in grave risk of being harmed," he said.
