OAKLAND -- Passengers on an AC Transit bus were showered with broken glass when the bus was hit by stray gunfire from a shooting at an East Oakland gas station only about a block away from a police substation.

Neither the intended target of the gunman nor another person whose car was struck as she pumped gas at the same station was wounded, police said. Both of those people ran away before police arrived and had not been located.

The shooting happened just after 11 a.m. at the Valero gas station at the intersection of 73rd and Bancroft avenues. Sgt. Steve Nowak said that, for unknown reasons, the gunman opened fire from adjacent Halliday Avenue on a man putting gas into his Camaro.

The man's car was hit, but he was not. The gunfire also hit a Lexus whose female driver was also pumping gas. The woman was not hit.

An AC Transit route 40 bus, carrying about 20 passengers, was hit by one of the stray bullets. Two people on the bus said they were showered by glass shards as the windows broke.

"It was scary, very scary," said Gloria Parker, 58, of Oakland. "We were sitting there in the line of fire."

Parker said as the shot hit the bus, she dove for cover and threw herself on top of a 3-year-old girl in a nearby seat.

The bus drove to the Eastmont substation about two blocks away, where the passengers were being checked and interviewed by police.
