Officials with MedFlight said one of their helicopters has been taken out of service after a bullet hole was discovered in the side of the aircraft on Thursday evening.
Todd Bailey, MedFlight's director of business development, said it is believed that the bullet struck the helicopter while it was in flight, and not when it was sitting on the ground, 10TV News reported.
No crew members or patients were injured.
According to Bailey, the bullet hole was found on the right side of the helicopter, just below the rear clam shell doors. He also said investigators found what appeared to be a bullet slug lying loose beneath the helicopter's floor.
Backup resources were being used to cover transports while Medflight 2 is out of service, Bailey said.
The aircraft is based on Wilbur Road in Marysville, according to MedFlight's Web site.
The investigation is ongoing.
