Vandals smashed wing mirrors on 15 cars in Belper during a night-time wrecking spree.
The vehicles were damaged sometime overnight between Friday, December 20 and Saturday, December 21, while parked on Belper Lane.
PCSO Eve Shaw of the Belper Town Safer Neighbourhood Policing Team has been carrying out enquiries in the local area.
She said: “Wing mirrors can be costly to replace and can cause inconvenience to the owner, who has to organise the repairs. We would really like to hear from anyone who may have any information about these incidents.
“I would also ask local residents and motorists to be vigilant, and to contact the police if they notice anything suspicious in the area.”
Anyone with information should contact Derbyshire police on 101.
