P Diddy arrested over assault on his son's American football coach

Rapper P Diddy has been arrested by police in California over claims he hit a sports coach with a gym weight.

Officers at UCLA university in Los Angeles had to deal with an altercation at the college training complex.

The rapper, whose real name is Sean Combs, has a son called Justin who plays as a defensive back on the American football team.

Nobody was seriously injured and Combs was released from a Los Angeles County jail after posting bail.

He's charged with assault with a deadly weapon.

The dispute, which involved a gym kettlebell, took place in the office of UCLA assistant coach Sal Alosi.

It's reported that a team assistant was shouting at Justin Combs repeatedly during a game which P Diddy was attending.

He's then said to have confronted the coach in his office after the match.

"This is an unfortunate incident for all parties involved," football coach Jim Mora said in the statement from UCLA campus police.

"While UCPD continues to review this matter, we will let the legal process run its course and refrain from further comment at this time."

The 45-year-old has built a music empire over 25 years and changed his name from Puff Daddy to Diddy.

In the UK, due to a legal dispute with a DJ, he's continued to release music under the name P Diddy.

As well as launching the careers of The Notorious BIG, he's promoted the careers of major international artists from Mary J Blige to Mariah Carey.

His 1997 debut album No Way Out went seven times platinum and he's won three Grammy Awards and two MTV Video Awards.

In 1998, he launched a clothing line, Sean John, which won the 2004 Council of Fashion Designers of America award for Menswear Designer of the Year.

The producer was involved in controversy when in a relationship with Jennifer Lopez in 1999.

He was charged with four counts of illegal gun possession while out at a nightclub.

Another man, connected to the rapper, was found guilty of assault and reckless endangerment after shots were fired inside the club which injured three people.

Sean Combs was cleared of all charges.

Combs was also arrested in 1999 for his involvement in the beating of former Interscope executive Steve Stoute in New York.

The rapper apologised, the charges were reduced and he was ordered to attend an anger management class.

Combs went into reality television with the premiere of his VH1 series I Want to Work for Diddy in 2008.

According to the Forbes hip-hop wealthiest list 2015, his personal fortune is estimated at close to £465m.
