A boy was stabbed in the face and beaten during a fight Thursday evening at the Santa Rosa Transit Mall. Police said they believed the incident was gang-related, and detectives from the gang task force had detained at least one suspect.

A transit mall service representative who declined to give his name said the fight began shortly after 7 p.m. after he asked a group of four young men standing on the sidewalk to move away from a bathroom door.

"The kids were blocking the entrance," the transit mall worker said. "I told them to move and all of a sudden, three of them started beating up the fourth kid."

He said the fight went on for a few minutes and when two bus drivers tried to break it up, one of them got "punched in the left eye" by one of the boys.

At this point, the boy who was being attacked reportedly ran across B Street toward the Sears parking lot, chased by the other three. The boy was then stabbed in the left cheek with an unknown weapon, Santa Rosa police said.

Police discovered the injured boy inside the transit mall, and he was taken to Santa Rosa Memorial Hospital for treatment.

The transit mall worker said the victim and suspects looked to be between 16 and 20 years old, and police said they believed all four were minors.

The transit representative said the mall and all the buses were equipped with cameras.

"They probably have the whole thing on tape," he said.
