Teen faces court after 'horrific' crash

A teen accused of being behind the wheel of a car that crashed and killed two girls will remain behind bars.

Detective Acting Inspector Travis Mills, officer in charge of road policing, said the 16-year-old boy did not apply for bail when he faced the ACT Children's Court on Monday, where he was remanded in custody.

The boy is charged with a string of offences including two counts of culpable driving causing death.

He will next face court later this month.

Police were set to oppose bail if the teen applied.

It is alleged the boy was driving a Toyota sedan when it smashed into a tree off the Monaro Highway at Hume on Sunday morning.

Two teenage girls aged 14 and 15 were found dead at the scene.

Acting Insp Mills described the crime scene as "horrific and graphic".

"Please have the conversation with your families about what you are expected to do on our roads as a road user," he said.

"It might be a confronting conversation ... but it may actually see you returning home.

"This was a tragic loss of life that need not have occurred."

It's alleged the driver and another passenger known to the girls fled the crash, leaving behind the dead passengers.

Police later found the two teens alleged to have run off.

A police spokesperson said they had received medical attention and were assisting major collision investigators with their inquiries.

The deaths bring the ACT road toll this year to 14.

Anyone who witnessed the crash or has dashcam footage is urged to contact Crime Stoppers.
