Police say Motley Crue frontman Vince Neil is accused of grabbing a woman's hair from behind and pulling her to the ground at a Las Vegas Strip resort.
Bystander cellphone video provided to the celebrity website TMZ.com shows actor Nicolas Cage physically restraining Neil before police arrived.
Las Vegas police Officer Michael Rodriguez said Friday the incident happened a little before 5:30 p.m. Thursday outside the Aria resort.
He confirmed that Cage was at the scene, but wasn't accused of a crime.
Police issued the 55-year-old Neil a misdemeanor battery summons and he's has a June 17 court date. He wasn't jailed.
His attorney, David Chesnoff, says he's investigating the allegation and the public shouldn't prejudge the situation.
A spokesman for Cage didn't immediately respond to messages.
