A man has handed himself in to police after seeing news reports of the Braddon hit and run that left two teenagers in hospital, one with horrific injuries.
A 35-year-old Harrison man went into Gungahlin Police Station on Tuesday, three days after a white ute mowed down two 19-year-olds walking home along Henty Street about 5.30am after a night out partying.
The incident was captured on CCTV cameras in the area.
Burma Han remains in an induced coma.
Police would not say whether the man made a confession, but say they found the offending vehicle at his house.
No charges have yet been laid, and the man is not in police custody.
He is only being treated as a suspect at this stage, and police are urging the public not to pre-judge the man.
Collision Investigation and Reconstruction Team acting Sergeant Graeme Cooper said the man had come forward after seeing media reports of the hit and run.
"It's very early in our investigation, we have a number of avenues of inquiry that we still have to explore, but he is certainly assisting us with our inquiries," acting Sergeant Cooper said.
"The assistance we've received from the media has been fantastic, and information that has been coming in from members of the public has been very beneficial," he said.
The crash left Burma Han, 19, with a broken neck and serious head injuries. He is still receiving specialist care in Sydney and is believed to be in an induced coma. The second teenager suffered less severe injuries and has been released from hospital.
Police are still investigating whether there was a pre-existing link between the driver and the victim.
Acting Sergeant Cooper said there was a vast amount of information about the crime circulating on social media, much of which was incorrect.
That included inaccurate reports that there may have been a scuffle immediately before the crash.
Police say they are pleased the hit and run appeared close to being resolved just four days after the crime.
