Police have issued a warning after reports of youngsters throwing stones and snowballs at cars.
Officers said this has been taking place on a ‘regular basis’ in the evenings on Hyndburn Road in Accrington, in particular from the Oxford Road side near the junction and Matalan.
A spokesman for the Central and Springhill Neighbourhood Policing Teams said: “Patrols have increased in the area and community representatives have been liaised with about the problem.
“We would urge, particularly local residents in the Frederick Street, Steiner and Portland Street areas, to contact us if they have any information regarding the youths responsible.
“There has already been one very serious road collision in this area not to long ago and nobody wants a repeat of this.”
Anyone with information call police on 101 or email Accrington.NPT@lancashire.pnn.police.uk.
