Word of 50 Cent's upcoming, "surprise" concert in his old South Jamaica, Queens neighborhood has already made rounds on the internet, but the Queens rapper has more to worry about than leaky press.

Police officials have expressed concerns that 50's Aug 30th performance, following his benefit concert at Six Flags the previous day, will spark violence in the neighborhood. The show is set to take place at the P.S. 30 schoolyard, just a few blocks from where the rapper was shot back in 2000 and cops worry that history could repeat itself.

A spokesperson from the Parks Department said that there was no performance mentioned on the permit for the event, but the New York Post reports that the NYPD will call in the help of their gang units to patrol the 20-block span around the South Jamaica Houses and control an expected crowd of 10,000 onlookers.

An unnamed source told the Post they believed that, "They're gonna take a shot at him, and they're either gonna hit him or they're gonna miss him and hit some poor, innocent kid or grandmother." 50's publicist has continued to insist that the rapper-turned-entrepreneur will only make an appearance at the event, which is sponsored by the New York Restoration Project, a charity collaboration between Bette Midler and the G-Unity Foundation.
