Man hit with wrench on head in BART attack, police and relative say

BART police are investigating an assault with a deadly weapon, possibly a wrench, that occurred Thursday at the BART Bay Fair Station in San Leandro.

Police said a man was sitting inside a train car at 7:31 p.m. when another man hit him in the head with an unknown metal object, and then punched and kicked him.

The man's sister-in-law messaged KTVU on Facebook to say the object was a wrench and that her brother-in-law had been traveling to home to Hayward from San Francisco where he works when he was hit on the back of the head.

A BART passenger used his cell phone to call the injured man's wife about what happened, she wrote. She declined to be interviewed further. Her brother-in-law went to the emergency room overnight but was released by Friday morning, she said.

The injured man told police the attack was unprovoked.

The suspect, described as a man in his late 30s, 6 feet tall, with a muscular build and wearing a gray shirt, tan shorts and black shoes, was not located.
