Dog walkers and joggers are to be given details of suspicious vehicles to look out on their early morning walks.
Volunteers are being urged by police to sign up to a new Neighbourhood Watch-style scheme in Bracknell, Berkshire. They will be given the details of the cars with a reference number and urged to call police if they spot them.
The police want about 50 volunteers, who will each cover three streets at the beginning of the day to give officers "a head start" in inquiries.
Insp Michael Squire, of Thames Valley Police, said: ‘The idea is to use the Neighbourhood Watch concept in a more proactive way. If we can mobilise about 50 people, who each cover two or three streets in their early morning walks, that means they can check more than 100 streets for suspicious vehicles. Their help will give our officers a head start in their inquiries, take these vehicles off the streets and assist in our drive to reduce crime and increase public protection.’
