NEW YORK - A 33-year-old man was killed and three other people were wounded in a shooting incident during a club gig in Manhattan on Wednesday (May 25) night, the New York Times said.

The victims were three men and one woman, the police said. The motive for the incident was unclear, and the police had not arrested anyone as of that night, they said.

The gig at Irving Plaza, a club in the Union Square area, was headlined by Grammy-winning rapper T.I., who was about to play when gunfire broke out, the report said.

According to witnesses, the club was packed with about 1,000 people, who started dashing for the exits.

T.I., 35, has scored two No.1 songs on the Billboard Hot 100 chart, Whatever You Like and Live Your Life, featuring Rihanna.

In 2008, he pleaded guilty to three charges of illegal weapons possession. He was sentenced to one year and one day in prison in 2009 and performed community service as part of his plea agreement, touring the United States to speak to young people about the dangers of drugs and gangs.
