Los Angeles County sheriff's Sgt. Arthur Famble Jr. says the rapper was arrested Thursday night after he destroyed the Sunset Strip nightclub's electronic soundboard.
The 20-year-old, whose real name is Tyler Gregory Okonma, was booked for investigation of felony vandalism and released on $20,000 bail.
The sergeant says that as the rapper was being led to a squad car, the crowd leaving the Roxy became angry and additional deputies were called in to disperse the crowd.
No one was hurt.
The rapper says in a Twitter message that he wasn't arrested.
