Chesterfield police have urged motorbike-owners to be alert after thieves struck several times in September.
In the latest incident, a white Yamaha motorcycle was stolen from a driveway on Church Close, Inkersall, at 9.55pm on Sunday, September 24.
It was the eighth bike reported stolen in Chesterfield last month, with thieves also striking in Dunston, Newbold, Holme Hall, Saltergate and Staveley.
Derbyshire Police have now urged owners to take precautions to avoid falling prey to criminals.
Inspector Russ Dakin, of Derbyshire Police’s community safety unit, said: “I would like to remind riders to make sure that they keep their bikes secure following these reports, as they can easily be wheeled away or loaded into a van or onto a trailer.
“It is worth considering extra steps to help prevent your bike from being stolen, such as securing them using a good quality chain to a permanent anchor point.”
He also suggested security devices such as alarms, immobilisers and secondary locks to fend off would-be thieves, and warned that vehicles should be left out of sight when possible.
Inspector Dakin added: “I would urge anyone who knows anything about the incidents or who sees anything suspicious to contact us.”
