Police in Alfreton are appealing for the owners of more than a dozen bikes that have been recovered by officers to come forward.
The 15 bicycles and one mini-motorbike were recovered from a house in Somercotes on Tuesday, April 2.
The mini-motorbike is blue and white with the words ‘White Knuckle’ written on the side.
No one at the address has been charged or arrested at the moment, but officers say they are pursuing lines of enquiry.
The recovered bicycles range in size and colours including green, pink, purple, silver, black and white.
There are both women’s and men’s mountain bikes and one road bike.
Some have had their wheels and handle-bars removed but several have distinctive writing on the frame.
Anyone in the area who has lost a bike or had one stolen recently is asked to contact PC Chris Anthony on 101 to try to identify their bicycle.
Residents are being asked to ensure all outbuildings are secure and expensive items are kept out of sight.
A spokesperson for Derbyshire police said: “If you have information about thefts of bikes or anyone acting suspiciously in the Alfreton, Somercotes and Leabrooks areas contact Derbyshire police on 101.
“Alternatively you can call Crimestoppers anonymously on 0800 555 111.”
