FIGHT FIGHT FIGHT With UCLA Football Coach

10:02 PM PT -- Diddy was released after posting $50,000 bail. According to the university, Diddy was charged with three counts of assault with a deadly weapon, one count of making terrorist threats and one count of battery.


6:50 PM PT -- Diddy was cuffed in the back of a campus patrol car as officers transferred him to L.A. County jail.
4:35 PM PT -- Sources connected with Diddy tells us the rap mogul is adamant he acted in SELF DEFENSE and was not the aggressor.
Our Diddy sources tell us ... Diddy insists the drama began during a workout session yesterday because strength and conditioning coach Sal Alosi was "riding Justin badly" and told him not to come back until the end of the summer.
Diddy went to the campus today to speak with Alosi -- believing he has an "issue" with Justin -- but things didn't go well when he arrived to campus.
Our Diddy sources say the coach would not see him and staff told him to leave ... but Diddy went to Alosi's office instead where Alosi told him to get out and threatened to call security if he didn't leave.
We're told Diddy said, "Fine, I'll call police" ... and Alosi snapped -- going after Diddy with his hands.
We're told Diddy insists he grabbed a kettlebell and held it up in a defensive position ... but did not attack with an intent to injure the coach.
4:15 PM PT -- Our UCLA sources tell us Diddy confronted Strength and Conditioning Coach Sal Alosi while Alosi was on the phone. We're told Diddy was told to "hang on" but he wasn't having it and picked up a kettlebell and swung it, narrowly missing Alosi. One source said if Diddy had connected, it could have killed Alosi.

 

We're also told the entire altercation is on video.

And get this ... we're told Diddy is referred to by the UCLA staff as a "helicopter dad" for hovering over practices.
By the way ... Alosi is infamous in his own right. He was a NY Jets coach who was suspended by the NFL in 2010 after tripping a Miami Dolphins player who was covering a punt.

P. Diddy has been arrested for allegedly getting into a fight with a football coach at UCLA ... where his son is on the team, 24WHZ Sports has learned.

We're told Campus Police took the music mogul into custody early Monday afternoon. Diddy's son, Justin Combs, is a defensive back on the team. We're told the fight went down at the UCLA athletic facility.
One source says a strength and conditioning coach was screaming at Justin on the field during a strength and conditioning session. We're told the coach "was riding Justin, screaming intensely at him." Diddy watched the whole thing from the sideline.
At some point later, we're told Diddy confronted the coach in his office and grabbed him. Diddy was arrested for assault.
A source connected with Diddy tells 24WHZ Diddy himself initially wanted to call police, but the phone was taken out of his hands.  
Diddy is still in custody at campus jail.

It's not uncommon for Diddy, who lives mostly in L.A. now, to be on campus for UCLA football practices. We got video of him roaming the sidelines back in April.
