Police are hunting a duo who used a moped to snatch a victim's car keys while she waited at traffic lights.
At approximately 1.45am on Thursday a woman had stopped in her car at traffic lights at the junction of Buckingham Road, Elmhurst Road and Weedon Road.
A moped ridden by two people stopped behind her.
The passenger got off the moped, opened the driver side door of the womans car and demanded that she got out of the car and give him the keys. He then leaned into the car and grabbed the car keys from the ignition.
He then got back on the moped and rode away, turned right in to Elmhurst Road. They rode along Bierton Road in to Cambridge Street and travelled along Upper Hundreds Way.
The victims car keys were stolen during the incident.
Investigating officer Detective Constable Emma Francis, based at Aylesbury Police Station, said: "This incident took place in the early hours of the morning when the roads are quiet so I'm appealing for anyone who may have witnessed this incident, or may have any CCTV or dash-cam footage along these roads at the time of the offence."
