A 27-year-old woman, who is also from the town, was arrested at the same time on suspicion of assisting an offender.
They are both in police custody.
The officer, who is based in Aylesbury, tried to stop the red Vauxhall Astra but it drove off and was involved in two other collisions before it was abandoned in nearby Osier Way.
The driver and two passengers fled the scene, a force spokesman said.
No-one was injured in the other crashes.
The force reiterated its appeal for witnesses or anyone with information, mobile phone or dash cam footage to call police on 101 quoting 747 (13/2).
