Police chased a suspicious vehicle which refused to stop last night.
Officers had first come across the car, reported to be a silver Vauxhall Corsa, in Town Lane Chartham Hatch at 11.15pm.
The car failed to stop for them, prompting the police helicopter to join the hunt.
Units pursued the car to the other side of Canterbury at Fordwich Road where the driver ran off. Four police cars were seen in the area.
Kent Police spokesman Natalie Hardy said: “A search of the area was carried out but no one was located. Enquiries into the circumstances of the incident are ongoing.”
