OAKLAND — A man captured on surveillance video photos and suspected in two recent violent attacks on BART train passengers was arrested Monday, police said.

Police identified the man as Mario Christopher Washington, a 42-year-old Berkeley resident, according to BART. Officers took Washington into custody just hours after the transit agency released images of the man caught on video, said BART spokesman Jim Allison. Train surveillance cameras captured the video.

An Oakland fire inspector spotted Washington at 9th Street and Broadway in downtown Oakland at 8:40 a.m. and recognized him from the surveillance footage, Allison said. He called police and officers arrested Washington on suspicion of assault with a deadly weapon.

The most recent of the two attacks happened Saturday on a San Francisco-bound train that was approaching the Embarcadero Station. That confrontation happened two days after an attack on a Fremont-bound train that was pulling into the Bay Fair station in San Leandro.

Both attacks were unprovoked, police said.

The Saturday attack happened around 7:30 p.m., when police say the suspect approached another man on the train and punched him twice in the face. The victim did not know the suspect, police said. He received medical treatment at the scene and was OK, police said.

On Aug. 3, the same man approached another person and hit him in the head with a bolt cutter, punched him and kicked him, police said. He then ran out of the train and from the station, police said.

Medics treated the man for a cut to his head and went by ambulance to a hospital. His injuries were not life-threatening.

At a Monday morning press conference, Deputy Police Chief Ed Alvarez told the assembled media that the public “will see more officers” on the trains.

Police and security officers were not present during the attacks, police said.
