A teenager will front court today after allegedly stealing a BMW and fleeing from police in a pursuit across western Sydney, before crashing into a medical centre overnight. 

Police spotted a BMW SUV at 11.35pm on the Northern Road in Cranebrook, after it was reportedly stolen from a hotel in Cambridge Park earlier that night.

The 16-year-old allegedly failed to stop for police, sparking a pursuit.

Officers called off the pursuit due to safety concerns, however, they continued to monitor the car.

Just after midnight, the BMW crashed into a Mitsubishi SUV with a female driver inside on the Great Western Highway in St Marys.

The collision sent the BMW into the front of a medical centre nearby.

The woman in the Mitsubishi was taken to hospital as a precaution and has since been released.

The 16-year-old boy suffered minor injuries. He was taken to hospital under police guard and police.

He was released and taken to St Marys police station where he was charged with several offences, including police pursuit and taking a vehicle without consent.

He was refused bail and will appear in children’s court today.
