There's been reports of people's cars having bricks, stones and bits of concrete thrown at them by men in a white van in South Derbyshire.
According to police there have been incidents in Hatton, Findern, and Hilton this month and they want to speak to anyone who's either seen it, or had it happen to them.
Officers say all the victims were driving their vehicles at the time, and it usually happened between 2pm and 3pm.
People in towns across South Derbyshire have reported bricks, stones and bits of concrete being thrown at their cars from a white transit van.
Police want to hear from anyone who may have seen the white transit van.
Sergeant Graham Summers, who is in charge of neighbourhood policing for South Derbyshire, said: “These motiveless acts of damage are completely reckless.
“All the victims have been driving their vehicles when the incident has happened and as well as the obvious danger being caused to them there is a clear danger to other road users as the driver’s attention is distracted.
“The only description we have is that the objects were thrown from a white transit type van and on one of the occasions there were said to be three people wearing high-visibility jackets in the front of the van.
“We would ask that if anyone has seen anything suspicious or thinks that they may have dash-cam footage that they make contact with us.
“We are also aware that there may be more victims that have not reported the incident to us and so we would also ask that they let us know.”
