St Kilda Boat Sales -

The body of a man has been found handcuffed to the steering wheel of a car that had plunged into a St Kilda Marina.

Police and ambulance crews were called to the St Kilda Marina early this morning after receiving reports of a car boot visible from the water's surface.

The car, which was found only a few metres from a boat ramp, was fully submerged by the time emergency units arrived.

Police divers inspecting the vehicle discovered the body of a man sitting in the driver's seat with his arm handcuffed to the steering wheel.

The car was dragged from the water shortly later.

The death was not being treated as suspicious, police said.
