OAKLAND, Calif.—A TV news cameraman is back at work after a group of young men punched him and stole his camera while he was on assignment on a busy Oakland street.

Wednesday's attack occurred as KPIX-TV cameraman Gregg Welk and reporter Anne Mackovec were wrapping up a story about the passing of Proposition 30 outside Oakland Technical High School for the station's noon newscast in north Oakland.

Station spokeswoman Akilah Bolden-Monifa said Welk was confronted by a group of young men who hit him and ran off with his camera to a car.

Bolden-Monifa said Welk sought medical treatment on his own and was back at work on Thursday. Mackovec was not injured.

The attack was the latest among a series of incidents involving journalists in Oakland within the past year, including the attack of a KGO-TV cameraman while covering a murder near the Occupy Oakland encampment.
