Car windows across San Ramon were shot out last night by someone with a BB gun, police said.
Sgt. Mike Boehrer said windows in about 20 cars were shot overnight. He said the incidents centered in the areas of Canyon Creek, Shadow Mountain Drive and Canyon Crest sometime after midnight.
Boehrer said there are some simple precautions people can take.
"Leave porch lights on and pay attention to vehicles parked in the area that don't look like the belong there, and report any suspicious activity," he said.
Boehrer said there are no suspects yet.
