Investigators open criminal probe into LA explosion

Police and fire investigators launched a criminal probe Sunday into the cause of an explosion at a hash oil manufacturer in downtown Los Angeles that sent firefighters running for their lives. Detectives from the Los Angeles Police Department's major crimes division were working with the city Fire Department's arson investigators to determine what might have sparked the blast that shot a ball of flames out of the building Saturday night and scorched a fire truck across the street, police spokesman Josh Rubenstein said. The federal Bureau of Alcohol, Tobacco, Firearms and Explosives was assisting local fire investigators, an agency spokeswoman said.
