While Jay and Beyoncé were up on stage putting on an epic performance at the Rose Bowl in Los Angeles, some members of the audience perhaps got a little bit too excited. There were 10 arrests during the concert -- with the most bizarre being a man who allegedly bit off the finger of another man in a dispute.

According to CBS Los Angeles, Roberto Alcaraz Garnica, 25, was arrested when he bite off a chunk of another man's finger in an altercation that started when Garnica "groped a woman at the stadium."

The woman happened to be the victim's girlfriend, and when he tried to retaliate, things got weird.

"During the altercation, the suspect bit the victim, causing serious injury to his finger. He lost the tip of one of his fingers," Lieutenant John Luna of the Pasadena Police Department told the Pasadena Star-News.

The unnamed victim was taken to the hospital, while Garnica was arrested on mayhem charges.

It's still unclear whether the girlfriend accompanied the victim to the hospital. With Jay and Beyoncé performing a once in a lifetime show, it would be hard to argue against the idea of sticking around, if she decided to stay through the concert.

A few other audience members were arrested -- most for public intoxication, with two being caught for scalping tickets.  Not bad for the amount of people at the show; around 55,000 people were in attendance for the sold-out concert.

With rumors swirling about Jay and Beyoncé regarding their supposed dissolving marriage; on stage there were no questions. The couple looked 'crazy in love' and that they were having a great time.

Maybe that's the whole point of show business, but the two certainly know how to put on an act.
