Ornge helicopter forced to land in Toronto park

An Ornge air ambulance helicopter made an emergency landing Friday in an Etobicoke park after a door opened during flight.

Two pilots and two medics were on board when the helicopter landed in Colonel Samuel Smith Park near Humber College's Lakeshore campus at Kipling and Lakeshore avenues.

No one was injured and no patients were on board.

The helicopter suffered some internal damage.

The helicopter will remain in the park until an investigation by the Transportation Safety Board is complete.
