Diddy arrested today after fighting a coach at UCLA where his son Justin plays football.

According to TMZ, Diddy attacked a UCLA coach after the coach got too aggressive with his son, screaming at him during a strength and conditioning session.

Reports say Diddy attacked the coach in his office after the training session. Diddy is said to have swung a heavy kettleball in the coach’s direction but missed. It’s a good thing he missed too because that could have killed him.

Reps for Diddy say the rap mogul acted in self defense and was not the aggressor in the attack.
