Police sources tell the website evidence suggests a club promoter was directly involved in the robbery. Apparently, the culprits mentioned $50,000 in cash Brown had just received from appearing at a local nightclub. It was also clear the robbers knew the home belonged to the “Ayo” performer.

Sources in Brown’s camp are confirming he was hit by people he knew well. The authorities also suspect the incident involved Blood gang members. The Los Angeles Police Department’s Gang Unit was assigned to the case.

Brown has been tied to the Bloods in the past. Last year, CB denied being an official member of any gang set, but he did tell MTV he is acquainted with known gang members.

“When you’re in L.A. and you’re around people, you meet everybody. You meet Crips. You meet Bloods,” said Brown. “Especially in this industry that I’m in. I’m not in the country world. I’m not in the all the way pop world. You in Hip Hop.”
