An Indigenous teenager has died in a Sydney hospital after colliding with an unmarked police car as his family demands an independent investigation into the crash.
Jai Wright died on Tuesday morning at Sydney's Prince Alfred Hospital after suffering critical head injuries in the accident, NSW Police said.
The teen was riding a trail bike when he collided with the undercover police car in inner-city Alexandria early Saturday morning.
The boy's father Lachlan Wright wants to know exactly how the accident happened.
"Finding out that the police were involved in Jai's death, that a police car and him had collided, was shocking to me, it just made my heart drop," he told reporters on Monday.
In an earlier statement, NSW Police said the trail bike was stolen along with a black Mercedes around 7am on Saturday before the collision took place.
Mr Wright said police had given him "inconsistent information" about his son's death where one officer told him Jai was being pursued by a police car, while another relayed that it was a freak accident and the police vehicle was stationary.
"I just want the truth, as long as I know the complete truth then I will be happy," he said.
The case has sparked fury on social media with calls for accountability from Indigenous figures and organisations, and comparisons made with another Aboriginal teenager TJ Hickey, who was killed in Redfern in 2004.
NATSILS, the peak body for Aboriginal & Torres Strait Islander Legal Services, said "until there is accountability there will be no true justice".
Police said they are investigating "the circumstances surrounding the crash on behalf of the NSW State Coroner".
"The investigation will also be reviewed by the Professional Standards Command and independently oversighted by the Law Enforcement Conduct Commission.
Jai, a Dunghutti boy, came from Revesby in Sydney's southwest and was studying to be an electrical apprentice.
