A 14-year-old who sprinted from police after being caught behind the wheel of an allegedly stolen car has denied he protested his innocence on social media.

The young boy lashed out at 9NEWS when he was found walking the streets of North Adelaide today, hours after being released on bail.

“Keep recording, I’ll smash that camera hey,” the 14-year-old said.

“You are a ridiculous piece of s---, mate!”

The teen boasted about his actions on Facebook, posting a picture of arrest yesterday, with the words “I didn’t choose the thug life, the thug life chose me”.

But he today denied the post, saying “it wasn’t me who posted it, mother f-----“.

“It wasn’t me.”

His outburst came after his dramatic arrest was caught on camera.

The vision shows the teen trapped by a parking inspector as police close in on a white Toyota Sedan yesterday on Tynte Street.

Panicking, the boy bolts out of the car and runs into an apartment complex, but quickly hits a dead-end and is arrested at the scene.

Struggling at first, he appears desperate to pick up a cigarette before finally relenting, and being bundled into a patrol car.

Police are now probing whether the youngster may be behind the alleged robbery of the car’s owner at knifepoint on Archer Street about 11.30pm on Wednesday.

The victim had just left work when he was approached by a suspect who demanded his car keys before fleeing the scene in the vehicle.

After the carjacking, Victims’ Rights Commissioner Michael O’Connell said posting to social media can cause more pain to the victim who was allegedly robbed.

“It’s like giving the victim a slap in the face after having attacked them,” Mr O’Connell said.

“I find it abhorrent and we should take steps to ensure it doesn’t happen again.”
