LOS ANGELES (AP) -- Authorities in Los Angeles say a woman who allegedly fired pepper spray at other customers during a Black Friday sale has surrendered to police.

Police Sgt. Jose Valle says the woman who allegedly caused minor injuries to 20 shoppers at a Los Angeles-area Walmart turned herself in Friday night.

He says she is currently not in custody but could face battery charges. Her identity was not released. Police plan to release more details Saturday morning.

The attack took place about 10:20 p.m. Thursday shortly after doors opened for the sale.

The store had brought out a crate of discounted Xbox video game players, and a crowd had formed to wait for the unwrapping.

Valle says the woman began spraying people in order to get an advantage.
