Well, that's not a headline you read every day. A young man who attended a Jay Z and Beyonce "On The Run" concert on Saturday night left the show with one finger less than he came with.

Reports say that Roberto Alcaraz-Garnica, 25-years old, attended the Rose Bowl show and lost a finger when he attempted to grope a concert goer's girlfriend. The boyfriend responded by biting Alcaraz-Garnica's finger off.

 Lt. John Luna of the Pasadena Police Department said of the incident, "The suspect sexually assaulted the female victim. The woman’s boyfriend confronted the alleged groper, and a fight ensued. During the altercation, the suspect bit the victim, causing serious injury to his finger."

"On The Run" tour has almost wrapped up in the States, with two more shows left in San Francisco before the couple heads overseas to Paris in September for another leg.
