South Australian Commissioner of Police Grant Stevens' son identified as teen critically injured after hit-and-run incident at Goolwa Beach during schoolies celebrations

The teenager who was seriously injured in a hit and run incident at Goolwa Beach overnight has been identified as the son of South Australian Commissioner of Police, Grant Stevens.

Commissioner Stevens' son, Charlie Stevens, was in Goolwa Beach near Victor Harbour celebrating schoolies on Friday when he was struck by a car at about 9pm.

He suffered serious injuries and was airlifted to Flinders Medical Centre where it was found he had sustained an irreversible brain injury.

He is currently on life support with his family who are waiting for family members from interstate to arrive.

The driver of the car, an 18-year-old Encounter Bay man, did not stop at the scene and was arrested by police who found him nearby on Port Elliot Road at Goolwa.

He was charged with causing harm by dangerous driving, aggravated driving without due care, leaving the scene of a serious crash and failing to truly answer questions.

The Encounter Bay man will appear in Christies Beach Magistrates Court on Monday November 20.

It is understood that Charlie attended Mercedes College and was a junior sportsman, who played football for the Mitcham Hawks team. 

His friends Mischa Reilley, 17, and Alayna Farley, 17, drove past the scene of the crash on the way to their accommodation on Friday night.

'At first I didn’t think much of it because we had already seen people get arrested by the police in Victor and closer to caravan parks,' Mischa told the Advertiser. 

'But then we noticed multiple ambulances and by their numbers we assumed it was something very serious.'

The tragic crash occurred less than 24-hours after Cmsr Stevens held a press conference announcing the death of Brevet Sergeant Jason Doig, 53, who was shot and died on a rural property in the nearby district of Senior.

More to come.
