Chris Brown was not in the best of moods a charity basketball game yesterday. 

The singer appeared to get into a confrontation with people in the crowd and it got heated enough that the cops needed to be called to calm the situation. 

It's not really clear who Chris is arguing with in the crowd as they seem to be blocked from view by members of Brown's security team. 

The incident happened at the Power 106 Celebrity Basketball Game at USC. It's hard to hear exactly what the argument was about as the music is quite loud but it's clear that whatever was said was enough to get Brown wound up over it.
