T.I. concert shooting: One dead and three injured at New York rap show

Witnesses say T.I. was not onstage when the shots were fired

One person has been killed and three more injured in a shooting at a concert in New York where hip hop artist T.I. was expected to perform.

The fatal incident occurred around 10.15pm in the third floor green room at Irving Plaza near Union Square in Manhattan.

According to police, a 33-year-old man was shot in the stomach and taken to hospital where he died a short time later.

A 34-year-old man was shot in the chest and is in critical condition. A 26-year-old woman and a 30-year-old man were both shot in the leg and are expected to survive.

Elijah Rodriguez was attending with his sister in the VIP area in front of the stage. He said T.I. was expected to go on stage at 9 or 9:30pm but "never showed up".

He said the venue started playing music again around 10pm, and at about 10.15 pm he saw a line of people coming out from where the performers were coming onstage.

"All the sudden I heard someone saying that there was a shot, that someone got shot," Rodriguez told the Associated Press.

Rodriguez added: "It was scary to deal with. When I got outside, like literally across the street, there were a few girls having panic attacks.

"One girl thought she saw someone get shot in front of her."

Video shot inside the venue showed a chaotic scene as concert goers rushed to the sides trying to leave the area as a group of people tended to a person on the floor.

Officers said no arrests have been made.
