NEW YORK, N.Y. (CBSMiami/AP) — Police have arrested a man who was captured on surveillance footage firing a gun outside the green room of a concert venue where hip-hop artist T.I. was set to perform.

Four people were shot, one of them fatally.

Brooklyn rapper, Roland Collins, 30, who goes by the stage name “Troy Ave” was arrested on weapons, menacing and reckless endangerment charges. Police said more charges are possible.

Collins also reportedly shot himself in the leg. He was scheduled to perform at the concert.

Police identified the slain man as Ronald McPhatter. Relatives say he worked as a bodyguard for Collins.

The dispute that started on an upper floor of the Manhattan venue traveled down to a second-floor balcony VIP area where shots rang out Wednesday night, police said.

“The girl next to me was shot point-blank, and men picked her up and carried her out,” witness Liv Hoffman told The Associated Press. “For two to three minutes, we still heard firing, still heard shots. We were clutching each other making sure no one was getting hit.”

Rapper T.I., whose real name is Clifford Joseph Harris Jr., was among the roughly 1,000 people in Irving Place at the time, authorities said. But performers Maino and Uncle Murda were on stage at the time of the shooting, said William Aubry, Manhattan chief of detectives.

T.I. was not among the injured.

The shooting marks the third time in a decade shootings have occurred during or after concerts where T.I. was to perform.

A member of the rapper’s entourage was killed and three others were injured during a gun battle following a post-concert party where T.I. performed near Cincinnati in 2006. Last March, two people were shot and injured in a Charlotte, North Carolina, nightclub where he was to perform.

In 2010, the Atlanta rapper was sentenced to 11 months in prison on federal gun charges.

Witnesses described a frantic, frightening scene that developed at around 10:15 p.m.

Video from inside the venue showed concertgoers rushing to the sides trying to leave the area as a group of people tended to a person on the floor.

“I ran out, just trying to look for my friends, just trying to see if everyone was OK. Everyone was hysterical,” Hoffman said.

A 34-year-old man was in critical but stable condition with a chest wound. A 26-year-old woman and a 30-year-old man with leg wounds were expected to survive.

Concertgoer Elijah Rodriguez said he had been in the VIP area by the stage.

“It was scary to deal with. When I got outside, like literally across the street, there were a few girls having, like, panic attacks. One girl thought she saw someone get shot in front of her,” Rodriguez said.

Police said metal detectors were set up at Irving Plaza, a 1,025-person ballroom-style music venue.

Witnesses said security getting into the concert was lax. Police say there was security in place, but how it was carried out is part of the investigation.

Irving Plaza is referring questions about the incident to police.
