(AP) A 33-year-old man is accused of biting two men in a seemingly random attack as the Arctic Monkeys performed at Chicago's Lollapalooza music festival.
Cook County State's Attorney's Office spokesman Steve Campbell says Sergio Vicenteno is charged with aggravated battery in the Aug. 1 attack. He has not entered a plea. Vicenteno's attorney, Michael Gillespie, did not return a call Friday morning.
Prosecutors say Vicenteno attacked one man, biting him in the shin. When a friend of the attacked man, Ben Lenet, tried to intervene, Vicenteno bit Lenet's arm. That bite broke Lenet's skin and drew blood.
The 29-year-old Lenet says another friend kicked the attacker, who got up and calmly walked away.
Lenet says he is taking antibiotics and has been tested for hepatitis and HIV.
