The Houston Fire Department was initially called out to reports of a fire in a building around 9:40 p.m. at the intersection of Fairway Park Drive and Mitchelldale Street, just northwest of Loop 610 along U.S. 290.
Firefighters had to cut their way in through garage doors, and they found fire along a wall that separates an office and warehouse. The fire was extinguished quickly.
The sprinkler system went off and had already taken care of much of the fire, fire department officials said.
The arson division is investigating, but the incident could have been an electrical fire, officials said.
No injuries were reported.
