The cause of an early Tuesday morning fire in a truck trailer at the rear of a Tulsa grocery store is under investigation.
The Tulsa Fire Department got the call just after 1 a.m. to the Las Americas store in the 2400 block of East Admiral Place near Lewis.
Firefighters were able to put the fire out quickly but not before it scorched the empty trailer and the rear loading dock door of the store.
They also had to clear smoke from the store. The department says no one was injured in the small fire.
Tulsa Fire Captain Stan May says the trailer fire was intentionally set. It then spread to the loading dock and the the roll up door of the store. They are still trying to determine how the fire was set.
