Teenager found in car after being stabbed near his home

A teenager who was stabbed near his home in Adelaide was found injured inside his car, witnesses say.

The 18-year-old was left with serious but non-life-threatening injuries after the stabbing yesterday on Leon Street in Salisbury North, north of Adelaide.

Witnesses told 9News the victim had only left his home four minutes before he was found with stab wounds just a few hundred metres away.

Family members ran to help the teenager after a nearby neighbour spotted him on Alexandra Street.

Neighbour Qassem Alhariri was one of the first on the scene after hearing the victim repeatedly honk his horn.

"I went to him and the car was full of blood and he was just shouting, 'Help me, help me'," Qassem Alhariri told 9News.

"It was pretty bad, like he had a couple of wounds to his stomach and then two to his thighs."

Friend Mohamad Alhariri said the victim remains in hospital being treated.

"I don't think we're allowed to go in until he comes out of emergency because he lost a lot of blood," he said.

SA Police believe it was not a random attack.

Anyone with information that may assist the investigation is asked to contact Crime Stoppers on 1800 333 000.
