A Beyoncé-Jay Z "On The Run" tour stop at the Rose Bowl Stadium yielded more than 10 arrests Saturday night, including that of a man who bit off the fingertip of another man after allegedly groping his girlfriend.

According to CBS Los Angeles, the Pasadena, California, police department reports that the confrontation between the two men arose when 25-year-old Roberto Alcaraz Garnica groped a woman at the concert venue.

The woman's boyfriend -- whose name has not been released by police -- confronted Garnica, who bit off a piece of the man's finger, sending him to the hospital. Garnica was arrested on a charge of mayhem, with further charges pending.

Garnica was not the only one arrested during that first night at Rose Bowl Stadium. Eight people were arrested for public drunkenness, according to the Pasadena Star-News, and two were nabbed for scalping tickets.
