Patrons reported a female creating a disturbance on the platform. The female suspect then began punching a female who was waiting for a train. Officers from SFPD and BART arrived and had to use minimal force to take the suspect into custody. The victim, who was apparently known to the suspect, suffered a scratch to her neck, an abrasion to her knee and a bite mark on her finger as a result of the attack. The victim placed the suspect under citizen's arrest for battery. The suspect had already been issued a prohibition order from a previous case, so she was cited for violation of that order and issued a new one. She was then booked into the San Francisco County Jail for battery and resisting arrest.
