Firefighters extinguished a five-alarm blaze that erupted on the roof of a vacant bowling alley in San Bernardino on Tuesday.
The fire broke out about 11:30 a.m. at the former San-Hi Lanes bowling alley on North Western Avenue near Highland Avenue, according to the San Bernardino City Fire Department.
Heavy smoke and fire were coming from the roof, which partially collapsed, according to fire department spokesman Tom Rubio.
About 100 firefighters from multiple agencies were on scene in an attempt to keep the blaze from spreading, Rubio said.
Firefighters atop ladder trucks poured water onto the building for more than three hours.
No bodies were found inside the structure, nor were any injuries reported.
The cause of the fire was under investigation and appeared to be suspicious, according to Rubio.
