Sean “Diddy” Combs was arrested at UCLA on Monday afternoon on a charge of assault with a deadly weapon after allegedly using a kettlebell to attack an assistant football coach, campus police confirmed.

According to a UCLA press release, no one was seriously injured by the kettlebell, a large cast-iron, ball-shaped weight with a single handle.

TMZ was first to report that the hip-hop mogul — formerly known as both Puff Daddy and P. Diddy — was apprehended after allegedly assaulting a coach who had been yelling at Diddy’s son, cornerback Justin Combs, during a strength and conditioning session. Combs then approached the coach at Acosta Athletic Training Complex, where he was arrested shortly after 12:30 p.m.

Combs was expected to be taken to the Los Angeles County Sheriff’s Department Inmate Reception Center on Monday evening.

The targeted assistant was reportedly strength coach Sal Alosi, who last made headlines nearly five years ago with the New York Jets. In a game on Dec. 12, 2010, Alosi stuck out his foot and tripped Miami Dolphins player Nolan Carroll near the sideline during a punt return. Alosi was fined and suspended for the season, and resigned the following January.

UCLA coach Jim Mora — himself a former longtime NFL assistant and head coach — hired Alosi on Jan. 10, 2012.

“I’m thankful that our staff showed the level of professionalism that they did in handling this situation,” Mora said in the statement. “This is an unfortunate incident for all parties involved. While UCPD continues to review this matter, we will let the legal process run its course and refrain from further comment at this time.”

Justin Combs is a redshirt junior who has played sparingly as a Bruin. The 5-foot-7 defensive back has appeared in seven games in two seasons, recording four tackles.
