Officers are releasing images of two bikes which were stolen during a burglary in Chesterfield as part of an appeal to trace them.
They were taken sometime between 2.30am and 3.15am on Wednesday 13 November from a garage attached to a house on Thornbridge Crescent, Birdholme.
We have an exact photo of one of the bikes which was stolen, an orange and black Sunn bike which had a baby carrier on the back.
The other photo is one like the bike which was stolen, an On One Scandal Bike, with Shimano gear set and black suspension forks with red adjusters on the top.
