Teenage pop sensation Justin Bieber is protesting the arrest of his record label vice-president after a riot broke out at a planned appearance in Long Island, New York last Friday.

A scheduled performance by Bieber at Roosevelt Field Mall drew such a large crowd Friday that Nassau Police had to be called in to control the melee. The show was eventually cancelled. The crowds had gathered to see the 15-year-old Canadian pop star — who released his first eight-song CD, My World, on Tuesday — give a performance at the tween clothing store, Justice.

One fan suffered a broke arm and scores more were nearly trampled when a riot broke out after mall bosses announced the appearance had been cancelled.

Def Jam VP James Rappo was led away from the shopping center in handcuffs after young Justin failed to Twitter a request to fans that his appearance had been scrapped in a timely fashion.

“The mall, I guess, should have had more security. They weren’t expecting 10,000 people to show up, Neither was I,” the singer said. “I’m gonna make T-shirts that say ‘Free Rappo,’” Justin joked during an interview with KIIS-FM’s “On-Air With Ryan Seacrest” Monday.

“I wanna see my fans. I don’t wanna look like a jerk, like a no-show… I wanna say hi to my fans, but when I got there the police threatened to put me in cuffs and take me and my mum to the penitentiary.
“They were threatening to put me in jail. They were like, ‘If you don’t pull off right now, we’re gonna arrest you and your mother,’” Justin explained.

“We’re not trying to get deported – me and my mum are Canadian. We were just like, ‘Whatever.’ So we pulled off, went away and it turns out the cops were holding another person… the vice-president of the label. They had him and were like, ‘If Justin doesn’t Twitter for everyone to go home, then we’re gonna send you to jail.’ My phone was dead; I had no clue what was going on. They sent him to jail because I didn’t Twitter on time,” Bieber adds.

“I’m very sorry for my fans. I’m really pleased everyone showed up.”
