A girl and young woman fought each other inside a Concord all-you-can-eat restaurant Thursday evening, according to police.

The 16-year-old and 19-year-old, both residents of Antioch, were arrested for battery, police said. Neither suspect was identified.

Police said they responded at 8:31 p.m. to a report of a fight at the Golden Corral Buffet & Grill located at 2050 Diamond Blvd.

When officers arrived, the fight had ended but a large crowd had gathered outside the restaurant.

Police determined by questioning multiple people including the two suspects that the fight broke out over a past conflict.

An 18-year-old man from Pittsburg was also arrested for an unrelated incident, according to police.

Anyone with additional information about the fight is asked to call Concord Police Department Detective Sgt. Mark Robison at (925) 671-5074.
