More information is coming out about Diddy's altercation with UCLA Strength and Conditioning Coach Sal Alosi, and insiders privy to the situation told TMZ that Alosi psychologically abused the music mogul's son. 

According to the source, the UCLA coach berated and belittled Justin for three years, emotionally breaking him down, and Diddy had enough of the situation after his son was told not to come back to practice for the rest of the summer. The Bad Boy CEO reportedly felt that he needed to talk to Alosi about the situation after baring witness to how Justin was treated by the coach over the years. 

The conversation didn't go as planned, and Diddy was subsequently arrested for allegedly attacked Alosi with a kettle bell weight. He has since been charged with three counts of assault with a deadly weapon, one count of making terrorist threats and one count of battery, but Diddy maintains that he was acting in self defense.
