Police are appealing for information after two separate armed robberies of pizza delivery drivers in Sydney’s south-west last night.

About 7.45pm (Saturday 5 April 2014), a pizza delivery driver arrived at a home on Mackenzie Street, Revesby, to make a delivery.

He was confronted outside the home by three men, one of whom was armed with a knife.

The men allegedly demanded the delivery driver place his wallet on the road, before taking it and fleeing on foot south on the M5 overpass into the southern end of Mackenzie Street.

The man carrying the knife has been described as being of Mediterranean/Middle Eastern appearance, 20-25 years old, 160-165cm tall, and unshaven with a medium build. He was last seen wearing a dark coloured T-shirt and dark coloured pants.

No description is available of the two other men. The driver was not injured.

The delivery driver contacted police, who attended along with a police dog. The dog was able to track a scent across the M5 overpass before losing it in Mackenzie Street.

In the second incident, about 9.55pm (Saturday 5 April 2014), a pizza delivery driver arrived at a home on Morotai Avenue, Riverwood, to make a delivery and noticed a man standing on the footpath.

As the driver took the pizzas out of the car, the man allegedly produced a knife and demanded money.

At this time, a second man, believed to be an accomplice, was seen walking towards the delivery driver’s car from Riverwood Park.

The first man allegedly ordered the driver to kneel on the ground and pass over his bag, before taking cash from the bag and the driver’s wallet from the car.

The two men then took the pizzas and ran into the nearby park.

The first man is described as being of Mediterranean/Middle Eastern appearance, 25-30 years old, 170cm tall, and clean shaven with a medium build. He was last seen wearing a black T-shirt and black track pants.

The second man is described as being of Mediterranean/Middle Eastern appearance, 25-30 years old, 170cm tall, and clean shaven with a medium build. He was last seen wearing a blue and white T-shirt, black knee-length pants, and a white baseball cap.

The delivery driver returned to his pizza store, where he reported the incident to his manager, who in turn contacted police. He was not injured.

Police from Bankstown and St George Local Area Commands are now appealing for anyone with information about the two incidents to contact police.
