Russellville firefighters are investigating an explosion at the Bestway Rent-To-Own store in the 300 block of Arkansas Street.
Firefighters say it started in a refrigerator. Someone had a bug bomb in it while it was still running and that caused the blast.
The explosion happened sometime after 7:00 Monday night when the store was closed and about half a dozen employees were leaving.
No one was hurt but all of the windows in the store were blown out.
