Ottawa Police say a man in his 20s is dead after a single-vehicle crash in Ottawa's rural south end.

Emergency crews responded to the crash on Franktown Road, west of Dwyer Hill Road, just after 1:30 a.m. Friday morning.

Ottawa Fire says the vehicle struck a hydro pole and ended up on its side in a ditch, with hydro wires across it.

Hydro Ottawa crews arrived on scene to secure the pole so emergency personnel could treat the patients.

Police say the passenger of the vehicle was pronounced dead at the scene and the driver received minor injuries.

The cause of the crash is under investigation. Police say they'll be looking at a number of factors into what may have caused it including weather, alcohol, speed or distraction.

Franktown Rd. was closed for several hours for the investigation. It reopened around 11 a.m.
