Police are appealing for more information after two off-road motorbikes have been seen riding around the Hadfield area over several days.
Both motorbikes were showing no registration plates - one was all black and the other orange.
They are also believed to have the numbers 34 and 52 or similar on the front of the bikes.
Police are asking locals if they know who is riding them or who owns/keeps them.
Anyone with any information is asked to contact PCSO 4415 Buller of the Hadfield Safer Neighbourhood Policing team via Derbyshire Police by calling 101, sending a direct message to @GlossopdaleSNT on Facebook or on Twitter @HadfieldSNT.
