At least one person is dead after a shooting at a T.I. concert in New York.

The rapper, whose real name is Clifford Harris, Jr., was scheduled to perform at the Irving Plaza music venue before shots rang out on the third floor green room at about 10:15 p.m., according to CNN. Although T.I. was at the venue, another act was performing when the shooting took place.

Some concertgoers have posted videos of the incident online which show people frantically running from the dance floor and trying to figure out what is happening. According to The New York Times, some concertgoers reported seeing a fight break out and move onto the stage just before the shots went off.

“There was a body that came across the stage, sort of with flailing arms,” concert attendee Paul Cantor, 34, told The Times..

Four people were reportedly shot. One 34-year-old man was shot in the chest, a 33-year-old man was shot in the stomach and two other people, a 26-year-old woman and a 30-year-old man, were shot in the leg. One of the male gunshot victims was pronounced dead at Beth Israel Hospital, according to ABC News.

T.I. was also supposed to perform at the 10AK club later that night, but that performance was cancelled.
