TULSA -- No suspicious devices were found after an hours-long bomb threat at a Tulsa school bus plant, says TCSO.
TCSO was called to investigate a bomb threat at the plant located at 2322 North Mingo Road after an employee of the plant received the threatening call.
The employee told officials the call came in around 12:30 from a man claiming there was a bomb in the plant and it was going to blow.
When the employee asked where the bomb was, the caller hung up and the plant was evacuated.
Several law enforcement agencies were then notified about the incident.
In total, four units and a bomb dog responded to the scene as well as the FBI. Bomb-sniffing dogs finished searching the plant just before 4 p.m. Monday.
The investigation has now been turned over to the FBI as the agency tries to determine who made the bomb threat.
