UCLA campus police have confirmed that rapper and business mogul Sean "Diddy" Combs is in custody Monday after being arrested shortly after 12:30 p.m. at UCLA's Acosta Athletic Training Complex on a charge of assault with a deadly weapon.
Diddy's son, Justin Combs, is a defensive back for the Bruins, and the rapper was attending the team's practice Monday morning prior to the incident. TMZ Sports reports that one of the team's assistant coaches "was screaming at Justin on the field."

According to Scout.com, a website that reports on the Bruin sports teams, Justin had missed some recent workouts and "wasn't giving a great effort Monday morning." UCLA strength and conditioning coach Sal Alosi reportedly kicked him out of the session.
Diddy then allegedly confronted the coach in his office with a kettlebell, hence the upgrade to "assault with a deadly weapon."
No one was seriously injured in the incident and UCPD is continuing to investigate.
Diddy was transported to the Los Angeles County Sheriff's Department Inmate Reception Center Monday evening and is being held on $30,000 bail.

UCLA football coach Jim Mora released a statement on the incident:
"I’m thankful that our staff showed the level of professionalism that they did in handling this situation. 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."
A day prior, on Father's Day, the hip-hop mogul's son shared a pic of a father-son flag football game.
