Police are appealing for information after three vehicles were damaged in Corby
A black Volkswagen Golf and a Royal Mail van were damaged in Stephenson Way.
The windscreen of a green Skoda Fabia was also smashed while it was parked in Welland Vale Road, near to the junction with Rockingham Road.
The incidents happened some time between 9am and 11.30am on Saturday, July 25, but the details have only just been released.
Police would particularly like to speak to the driver of a white van, who stopped and spoke to the Fabia driver and who officers believe may have information about the person who carried out the damage.
Witnesses, or anyone with information, are asked to call Northamptonshire Police on 101 or alternatively they can call the independent charity Crimestoppers anonymously on 0800 555 111.
