'My heart is heavy today': Rapper T.I. grieves over shooting at his New York concert that left one dead and three wounded - as shocking video emerges of the moment gunman opened fire 

Rapper T.I. has released a statement lamenting the shooting that left one dead and three wounded at his gig in New York City on Wednesday night.

A 33-year-old man died after being shot in the stomach at Irving Plaza concert hall at 10.15pm. 

Another man survived after being shot in the chest, and another was shot in the leg.

A woman, a 26-year-old model from the Bronx, also survived being shot in the leg, and later posted on Facebook: 'I'm SO VERY grateful for life'.

T.I., whose real name is Clifford Joseph Harris, Jr., made his first public comments about the incident on Instagram on Thursday.

The Atlanta-born 35-year-old said: 'My heart is heavy today. Our music is intended to save lives, like it has mine and many others. My heartfelt condolences to the family that suffered the loss & my prayers are with all those injured. Respectfully, Tip.'  

An aspiring rapper has been arrested for his role in the shooting, charged with attempted murder and criminal possession of two weapons.

The arrest came a few hours before New York City's police commissioner Bill Bratton called rap artists 'basically thugs'.

The city's top cop slammed rappers' actions in a WCBS radio interview as footage emerged of the chaos that unfolded as the shots were fired inside Irving Plaza. 

'The crazy world of these so-called rap artists who are basically thugs that basically celebrate violence they did all their lives.' Bratton said.

'Unfortunately, that violence often times manifests itself during their performances.'

He added: 'The background of a lot of these young people, they are significant artists in that world … but unfortunately the lifestyles that they lived … often time follows them into the entertainment world and the success they have in it.'

Brooklyn-based rapper Troy Ave, whose real name is Roland Collins, was arrested for his role in the shooting on Friday. He accidentally shot himself in the leg during the melee. 

Surveillance video of the incident shows a gunman entering the backstage VIP area with two other men before firing one shot and then fleeing. 

On cell phone video, gunshots can be heard in the small area backstage.

Troy, who was set to perform at the show, had a beef with Maino, the New York Daily News reported.

He had just left the stage when at least five shots rang out, sources said.

The source told the newspaper: 'There is clear video, very graphic video. He walks right out, women all around, and starts shooting his gun,' a source said.

'It's an ongoing rap group rivalry, him and Maino.'

Authorities said Thursday that 33-year-old Ronald McPhatter was fatally shot in the stomach during Wednesday night's shooting. 

His brother, Shanduke McPhatter, runs an anti-violence nonprofit called Gangstas Making Astronomical Community Changes. He hasn't returned a message. 

In addition, police say 26-year-old Maggie Heckstall was shot in the leg and 34-year-old Christopher Vinson was shot in the chest.

Collins, Heckstall and Vinson are in stable condition.

Investigators say it doesn't appear T.I. was involved in the dispute.

Live Hoffman, 19, was in the balcony VIP area to the left of the stage when the shooting happened. She said there had been some kind of argument between two groups of people before the shooting.

A girl she had been talking to was one of the victims. 'The girl next to me was shot point blank, and men picked her up and carried her out,' Hoffman said, still shaken by the events that unfolded right in front of her.

'For two-to-three minutes we still heard firing, still heard shots, we were clutching each other making sure no one was getting hit.'

Hoffman added: 'I ran out, just trying to look for my friends, just trying to see if everyone was OK. Everyone was hysterical.'  

Police said metal detectors were set up at Irving Plaza, a 1,025-person ballroom-style music venue, but witnesses said security getting into the concert was lax. 

Elijah Rodriguez was attending the concert with his sister and they were in the VIP area by the stage. 

He said T.I. was supposed to go on stage at 9pm or 9.30pm but 'he never showed up'.

Rappers Maino and Uncle Murda had been performing on stage at the time of the shooting.

He said that about 10pm the venue started playing music again, and at about 10.15pm, 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 said.

Rodriguez did not actually hear the shots himself.

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

'One girl thought she saw someone get shot in front of her,' he said, adding that T.I. was not onstage when the shots were fired.

Mayhem ensued inside the venue after gunshots rang out causing panicked concertgoers to flee for safety

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

'We saw, like, two people up on the VIP arguing, and then everybody started running because they heard the shots,' one witness told CBS2. 

'It was terrifying. We just kept running with everybody else because they were running for their lives, so we just started running, and I fell, and I got stomped on a little bit. My shoe came off.'

Another witness told the station: 'We had no idea where it was coming from, so we just were running out for the exit, you know, anywhere we possibly could.' 

Representatives for T.I., whose real name is Clifford Joseph Harris Jr., said they were referring all questions about the shooting to police. 

At the time of the shooting, at least 1,000 people were inside the venue, according to PIX11.

A concert attendant told the station that no one was searched when they entered the venue.

While police said there were metal detectors at the venue, they are investigating how someone apparently made it past with a gun.

Following the incident, the building was cleared as police investigated and searched for any other victims.

Early Thursday, Chief of Manhattan South Detectives William Aubry said in a news conference that police have recovered ballistic evidence, according to CBS2.  

T.I. was set to perform at Irving Plaza and then 1 OAK later on Wednesday, however the NYPD reportedly shut down the club.

The 35-year-old Atlanta rapper started in the music business in 2001 and is the founder of Grand Hustle Records. 

He has released nine studio albums and recorded hits such as Whatever You Like, Live your Life with Rihanna and About the Money with Young Thug.

He has also starred in several movies and television shows such as Boss and American Gangster.

In 2006, shots were fired at a show he performed at in Cincinnati during which his friend and personal assistant Philant Johnson was killed.
