A fire damaged a vacant office in the strip mall behind Fong Restaurant in El Centro.
El Centro Fire Capt. Ken Herbert said the department received a call around 3:30 a.m. regarding a fire behind the restaurant at 1461 S. Fourth St.
Herbert said the fire had already spread to the roof by the time firefighters arrived. The smoke could be seen a block away.
Three fire units responded to the fire, which Herbert said helped firefighters in containing the fire in about 15 minutes. The fire was extinguished shortly thereafter.
