LOS ANGELES — Hip-hop music mogul Diddy was released from jail after an alleged assault with a weight-room kettlebell at the athletic facilities of UCLA, where his son is on the football team, police said.

Diddy, 45, whose real name is Sean Combs, was freed late Monday night after posting bail, several hours after his afternoon arrest, jail records showed.

Officials did not identify the victim of the assault or say what led to it. No one was seriously injured, campus police said in a statement.

The jail records show that Combs’ bail was $160,000, but sheriff’s officials reached by phone said he posted $50,000. The reason for the discrepancy wasn’t clear.
