Stone-throwing yobs have been slammed for putting drivers in grave danger.
Police says gangs of youths have been pelting passing cars with rocks across Burnley.
Drivers have been targeted in Kiddrow Lane, Scott Street, Rossendale Road and Melrose Avenue in the two-week campaign of vandalism by gangs of teenagers and even children as young as 10.
Police say no-one has been hurt yet but a number of vehicles have been damaged. Officers have vowed to take tough action to put a stop to it.
Sgt Mick Burnett, of Burnley Police, said: “What is concerning is the potential to cause serious injury if drivers are forced to take evasive action. The consequences of these actions could be catastrophic. It has been happening in Scott Street and Kiddrow Lane and youths are taking cover behind the wall.
“We have also had incidents around Rossendale Road and on the Griffin Estate with damage caused to vehicles by a group of youths throwing stones. We are not going to tolerate this and are now taking positive action. We are working hard to identify them.”
Police believe there may be two separate groups of youths responsible for the attacks – one between 10 and 13 years old and another between 13 and 16.
The attacks have been happening between 8pm and 9-30pm and police are urging motorists to be vigilant.
Coun. Neil Mottershead said: “These actions are putting motorists in grave danger. If one of those stones smashes a window and distracts the driver they could end up on the pavement. As a councillor I am calling for these kids to stop before someone is hurt – or worse. If anyone sees these youths they should report it to the police.”
Anybody with information can call police on 101 or Crimestoppers 0800 555 111.
