Pleasant Hill, California, U.S. - Three incendiary devices touched off a blaze that destroyed the Diablo Valley College's police services building early Monday morning. The 40-foot by 60-foot wooden building was deemed unusable after burning for only about 20 minutes. No other nearby structures were damaged by the fire. Police set up a temporary operations center in a parking lot, until the school gave them a conference room in another building. No suspects or motive has been made public yet.
