OKLAHOMA CITY -- Fire crews raced to the 1500 block of SW 74th on the I-240 Service Road between Penn and Western.
About 3 a.m. firefighters found a small fire on the roof of a strip mall building.
Officials say the building is for lease and was empty.
Thursday workers were on top of the building using a saw to cut through the roof.
Firefighters think the fire started in the area where workers were making those repairs.
Fire investigators have not yet named a cause of the fire.
