A 25-year-old concert-goer was taken into custody on suspicion of sexual battery and mayhem after he allegedly groped a woman at Beyonce's and Jay Z's "On the Run" tour at the Rose Bowl and then bit off the tip of her boyfriend's finger during an ensuing fight, police said.
The incident occurred Saturday as an estimated 55,000 fans packed the outdoor venue for the first of two performances over the weekend.
Pasadena police Lt. John Luna told the Los Angeles Times that Robert Alcaraz-Garnica of San Diego bit the boyfriend's finger during the fight, causing a "serious injury." In an interview with the Pasadena Star-News, he said the victim "lost the tip of one of his fingers."
Alcaraz-Garnica was arrested inside the stadium and transferred to the L.A. County jail on Sunday on suspicion of sexual battery and mayhem, police said.
Ten other arrests were made at the concert Saturday - eight related to drunkenness and two related to ticket scalping, police said.
