A fire caused minor damage to a strip mall near 21st and Garnett early Friday morning in east Tulsa.
Tulsa Fire says the alarm sounded just before 1:15 a.m.
When firefighters arrived, they found a pile of trash on fire outside one of the buildings. Flames had reached the roof, but firefighters were still able to extinguish the blaze rather quickly.
No one was injured.
Who started the fire has yet to be determined.
