SAN FRANCISCO — A 17-year-old Oakland girl was arrested Wednesday night for her suspected involvement in the robbery of a BART train passenger’s computer, authorities said Thursday.

Two other suspects remain at large and the computer was not recovered, authorities said.

The robbery happened about 7:30 p.m. Wednesday on a Richmond-bound train as it was about to pull into BART’s 16th Street Station.

Authorities said a Concord man was sitting in an aisle seat using a MacBook laptop when a male snatched the computer from him and ran from the train at the station. Two other people, including the girl, were with the man who took the computer, authorities said.

Authorities said the girl attempted to block the computer owner from chasing the suspect who had taken the laptop. He was able to detain her and hold her near the station agent’s booth until police arrived.

The girl was arrested on suspicion of robbery of a train passenger.

No one was injured.

Anyone with information about the robbery may call BART police at 510-464-7040 or the anonymous tip line at 510-464-7000 or 911.
