Police investigate why hatchback in Menai double fatality crossed to other side of road

Updated

Police are appealing for dashcam footage and any other information which may explain what led to a head-on accident at Menai in which two people died.

The man, 23, of Bangor and woman, 23, of Yagoona were travelling in a Nissan Tida hatchback on the southbound side of Alfords Point Road about 4.40pm on Thursday when the vehicle veered to the other side of the road, colliding with a Toyota Hilux.

They died at the scene while the driver of the ute, a man, 46, was taken to St George Hospital, suffering a fractured wrist and rib injuries.

Police said the man and woman were "friends".

Acting commander of Sutherland Police Area Command, Acting Superintendent Steve Patton, said investigations continued into why the hatchback veered to the other side of the road.

"We are already examining some dashcam and appealing for anyone else who was driving on Alfords Point Road at the time of the accident or prior to that to come forward if they have more footage or other information," he said.

"They can call Sutherland Police Station or Crime Stoppers (1800 333 000)."

Mr Patton said at this early stage it did not appear speed was a factor.

The speed limit where the accident occurred, near the Old Illawarra Road intersection, is 80km/h
