A sergeant contacted an adult female for fare evasion. The female resisted the detention and fought with the sergeant. During the struggle, the suspect bit the sergeant. She was eventually taken into custody. She was found to have a valid stay away order to stay away from all BART stations. She was issued a prohibition order and placed on a psychiatric evaluation hold with a criminal hold for resisting arrest, battery on an officer and violation of the court order. She will be booked on those charges once she has been cleared for booking.
