OAKLAND—Three teenage girls have been arrested for allegedly beating a passenger on a train at the West Oakland BART station in February.

According to reports, the three suspects allegedly punched another female passenger in the head multiple times aboard a train at the West Oakland at 9 p.m. on February 27. On February 28, the victim reported the attack to BART authorities who has been investigating.

BART police detectives identified all four suspects based on the victim’s description and assistance from other witnesses, including a station agent who saw the suspects run out of the station after the assault. One suspect was arrested on Wednesday, May 3, the second suspect was arrested on Thursday, May 4 and a third suspect was apprehended on Friday, May 5. All three suspects, who are juveniles were booked into Alameda County Juvenile Hall on charges of battery resulting in great bodily injury. Police are still searching for the fourth suspect who has an outstanding warrant.

The latest arrest is the result of a trend of violent attacks on BART trains by teenagers. Two teenage boys were arrested after a mob of about 50 teens swarmed a BART train, beating and robbing several passengers. One of the suspects was taken into custody after a robbery attempt and police chase.

Cameras placed on the train cars captured high quality images of the suspects and were vital in arrests of several investigations.
