The Northern Territory Police Force are investigating after a crash in Darwin City overnight.

Around 12am, police observed a WA registered Toyota Single Cab Ute being driven by youths, travelling outbound on Cavanagh. Police attempted to conduct a traffic apprehension however the ute failed to stop at which time a pursuit was initiated for a short period of time, before being terminated for safety reasons.

A short time later, the ute drove through a red light at the intersection of Gardens Hill Road and Daly Street, colliding with a taxi.

The three occupants of the taxi, two males and female, were conveyed to hospital for treatment for non-life-threatening injuries.

A 15-year-old male was taken into custody at the scene. It is currently unknown if he was the driver of the ute, and he has since been released pending further enquiries. 

Two other unknown occupants of the ute, believed to be youths, fled the location on foot.

Investigations remain ongoing. 

Road closures were in place throughout the night and have since been lifted.

Due to the nature of the collision, the incident is also being investigated as a serious custody incident.

Police are urging anyone with information, particularly dash-cam footage, to come forward on 131 444. Anonymous reports can also be made through Crime Stoppers on 1800 333 000.
