Police are seeking information as investigations into a violent robbery at Manly West on the weekend continue.

Just before midday on Sunday, a 45-year-old man has driven his ute into a driveway on Peregian Close when another man has approached him from a black Toyota Corolla parked in the street.

A struggle took place between the two men before he drove off in the car, a silver Toyota Hilux.

As the ute’s driver has attempted to stop the man, he was run over by the vehicle and sustained serious injuries.

The Toyota Hilux was located abandoned in Amberjack Street a short time later.

Detectives are appealing to anyone who may have information that could identify the man or the Toyota Corolla to contact police.
