Mobile phone vouchers are being offered to young people in Surrey in exchange for information about graffiti vandals.
Surrey Police have said they will not tolerate graffiti vandalism
Crimestoppers has teamed up with the Mole Valley Safety Partnership to come up with the idea to try to stamp out the graffiti problem.
Anyone who gives police significant information about the vandals will be given up to £100 worth of phone credit.
Police hope the incentive will encourage young people to report crimes they see going on around them.
Pc Mike Bessant, crime reduction officer for the Mole Valley, said: "It is only a minority of people who get involved in this kind of thoughtless vandalism, most youngsters recognise it is stupid and costly.
"We know that many so called 'taggers' like to boast about what they do, and so it is likely that quite a few of their age group will know who is responsible.
"Many of the young people who carry out the graffiti are not aware that by doing so the could end up with a criminal record.
"Graffiti will not be tolerated and we are keen to hear from anyone that can help police by telling us who is damaging property in this way."
