Postman assaulted and carjacked in broad daylight in Adelaide

A delivery driver has been assaulted and his truck full of mail stolen as he was on the morning run in Adelaide's north today.

The driver was on Parnatti Street in Lightsview just before 8.40am when he was grabbed and assaulted before the offender drove off with his car.

Neighbours told 9News they have been left shaken by the daylight robbery.

"It is terrifying and scary, I always thought this street was very safe," Patience Showa said.

The car was captured driving down the street moments after the attack. It was then spotted 12 kilometres away but hasn't yet been found.

"It's quite weird as well that we didn't hear anything, not even any neighbours were outside, so just a bit shocking I guess," Caleb Pengilly said.

The driver's stomach was injured and he was treated by paramedics at the scene.

The attacker is described as Caucasian man in his 30s, wearing a baseball cap and black hooded jumper at the time.
