P. Diddy will NOT be charged with a crime in the UCLA football melee ... TMZ has learned.

As TMZ reported, Diddy got extremely angry after his son Justin was sent home from football practice by Sal Alosi, the Strength and Conditioning Coach for the team.

Diddy and his son went back to the school where things got hot and the mogul allegedly swung a kettlebell at the coach.

Sources familiar with the case tell us, the L.A. City Attorney will conduct an informal office hearing where Diddy will appear, accompanied by his lawyer, Mark Geragos, and others involved in the incident. The hearing is set for October 15th.

The hearing officer could simply warn Diddy not to fly off the handle again, or he could ask him to attend a few anger management classes.
