A suspicious bag on SkyWest Flight 4770 which operates as a Delta connection, shut down the Theodore Roosevelt Regional Airport in Dickinson Wednesday afternoon.
An unclaimed bag onboard began making a beeping noise, and the airplane was able to land safely and passengers were interviewed.
The Stark County Sheriff's Department is waiting for the Bismarck Bomb Squad to arrive on scene to investigate and clear the aircraft.
Several agencies responded to the airport.
A spokesperson from Delta says all passengers and crew safely deplaned.
