A man was shot and wounded during a robbery late Tuesday in the parking lot of the Bay Fair BART station in San Leandro, which was one of the transit system’s most crime-ridden stations last year.

The shooting happened outside the station at 15242 Hesperian Blvd. about 10:15 p.m. Tuesday.

Officers responding to reports of gunfire in the west parking lot found a man suffering from a gunshot wound to the chest, BART police said. The man, whose name wasn’t released, was taken to Eden Medical Center in Castro Valley, where he was reported to be in critical but stable condition.

Two possible assailants were seen driving south on Wagner Street after the shooting, authorities said.

The man was walking through the parking lot when he was approached by two men, said BART police Lt. Terence McCarty. He was robbed of his backpack and was shot during the confrontation, McCarty said.

BART police, who have a substation at Bay Fair, are investigating Tuesday night’s shooting. San Leandro police crime scene technicians collected evidence at the scene.

No arrests have been made.

A Chronicle analysis of crime statistics at BART’s 44 stations for the first 10 months of 2014 showed that the Bay Fair station was among the worst both for total violent crime and for crime per passenger traffic. BART police attributed the high crime numbers at Bay Fair to a gang that rode BART in central and southern Alameda County and committed crimes in the area during the summer.
