A Sunbury man was left "screaming in pain" in his driveway and seriously injured after being run over by his own car during a terrifying aggravated burglary this week.

Father of five James Wilkie, 47, suffered a fractured femur, five broken ribs and leg wounds after falling under the wheel of his own Jeep Cherokee while trying to stop a man from stealing it from the driveway of his Riddell Road home just after 4am on Tuesday.

Mr Wilkie had heard a noise outside his house and gone downstairs where he discovered a man starting his car.

When he tried to open the car door the offender sped off, hitting Mr Wilkie and leaving him lying in the driveway.
