According to Pasadena police, 11 people were arrested at the Beyoncé-Jay Z concert at the Rose Bowl Saturday night. Among the arrested was Roberto Alcaraz-Garnica, 25, of San Diego, who allegedly bit a man's fingertip off after groping the man's girlfriend.

Pasadena police Lt. John Luna told the Pasadena Star-News that eight people were arrested Saturday night for public drunkenness and two for ticket scalping at the venue. Alcaraz-Garnica, meanwhile, was arrested on "on suspicion of sexual battery and mayhem, legally defined as disabling or disfiguring a part of a victim's body."

"The suspect sexually assaulted the female victim," Luna said. "The woman's boyfriend confronted the alleged groper, and a fight ensued."

It was during that fight that Alcaraz-Garnica bit the man's fingertip off.
