A tragic start to Valentine's Day with a teenage boy dying in a single vehicle traffic crash in Manoora in the early hours of this morning.

Over the last 6 months record rises in stolen cars in the Cairns and Douglas regions have found teenagers offenders behind the wheel.

Preliminary investigations indicate at around 12.50am police observed an alleged stolen vehicle in Manoora.

The vehicle was sighted several times in the area before the driver lost control of the white hatchback at around 1.10am while travelling south on Pease Street.

The vehicle travelled across the north bound lanes before crashing into a tree, near Saltwater Creek.

All six teenage occupants of the car were injured. Police and ambulance officers performed CPR on a 14-year-old boy, a passenger in the vehicle, however he was pronounced deceased at the scene.

The 14-year-old male driver was taken to Cairns Hospital in a serious condition. Four other teenage passengers were also transported to hospital with non-life-threatening injuries, girls aged 12, 15 and 15 and a 14-year-old boy.

Queensland Ambulance said Multiple QAS crews, including critical care paramedics, responded to reports of a single-vehicle crash into a tree on Pease Street at 1.18am. Six patients were assessed at the scene and five patients were transported to Cairns Hospital, including:

A male teen with critical injuries.
A male teen with pelvic injuries in a serious but stable condition.
A male teen with chest injuries in a stable condition.
A female teen with abdominal, back and head injuries in a stable condition.
A female teen with neck injuries in a serious condition.
A female teen with an arm injury in a stable condition.

Police are appealing for anyone who saw the vehicle, a white 2010 Toyota Yaris hatchback, or has relevant dashcam vision to contact them.

Police are also appealing to the driver of a blue sedan, which the Yaris overtook on Pease Street at speed at around 1am to contact them. The blue sedan was travelling south bound over Salt Water Creek Bridge at the time. Police are urging the driver to make contact as soon as possible.

Investigators from the Forensic Crash Unit are investigating with oversight from the Ethical Standard Command.

It will be further alleged the Yaris had been stolen from a Manunda house sometime after 9pm on Sunday night (February 13).

All six teenagers are from Cairns.
