A movie production company was forced to begin its first day of shooting without Busta Rhymes after the New York Police Department raised security concerns.
The department declined to detail its specific concerns about Rhymes, who angered officers last year when he refused to cooperate with the investigation of his bodyguard's murder.
The man was shot during the filming of a music video.
Rhymes is a cast member in Order of Redemption, which began shooting Saturday in midtown Manhattan. The crime drama, starring Academy Award nominee Tom Berenger, is shooting scenes in New York City on 14 nonconsecutive days into early April.
The 34-year-old rapper, whose real name is Trevor Smith, refused to cooperate with a probe into the February 2006 slaying of Israel Ramirez. No arrests have been made in the shooting outside a Brooklyn recording studio.
The rap star has had several run-ins with law enforcement in the past year. Police say he has driven with a suspended license, beaten his former driver in a dispute over money and talked on a cellphone while driving.
