Police were called to the Wendy's near 90th and Maple Tuesday morning, after two employees reported being attacked by two men waiting at the closed drive thru.
The call initially came over the scanners as an "attempted robbery."
Police say employees arrived at the closed fast food restaurant to find a man banging on the drive thru window.
When the employees got out of the car, two men assaulted them both, and then fled in a Ford Explorer.
Police and paramedics were called out. One victim was transported for minor injuries.
Officers are investigating the attack as a case of misdemeanor assault.
