LINDEN, Calif. -- A security guard was struck across the head twice with his own baton during an attack Saturday, police said.

The 39-year-old male security guard was taken to San Joaquin Hospital with swelling to his left eye and a 7-to 8-inch laceration across his head, police said.

The incident happened at the La Botanita Bar on the 19400 block on East Highway 26.

Police are looking for three men in their 30s who were last seen driving from the scene of the attack heading westbound on Highway 26. They may be driving a black Dodge truck, officials said.
