At about 7:10 a.m., police received a call from someone reporting that a black cylindrical object was found attached to a transformer box in the 48000 block of Kato Road.
Fremont police Sgt. Chris Mazzone said the object is wrapped in electrical tape, has a battery attached to it and a red cap on top, and "looks like it could be an explosive device."
As of about 9:45 a.m. the Alameda County bomb squad was at the scene and evaluating the object. Kato Road is in an industrial area near Interstate Highway 880.
