A 36-year-old Coombs man is facing court after allegedly stealing two vehicles and driving on the wrong side of the road, causing a head-on collision.

Police say they received a report at about 9.30am on Saturday that a vehicle had been stolen after keys were taken from a locker at a Phillip gym.

The vehicle was later located at a shopping centre in Woden, where forensic examination was carried out before it was returned to the owner.

Police say they then received a report at about 11.15am that a white Skoda Scala had been stolen from a residence in Lyons.

A short time later, police were notified the stolen vehicle was being driven at high speed and on the wrong side of the road before colliding head-on with another vehicle in Yarralumla.

Witnesses prevented the man from leaving the scene and he was arrested by police.

The man has been charged with two counts of taking a motor vehicle without consent, two counts of driving a motor vehicle without consent, and dangerous driving.
