Offenders could be made to clean up their graffiti

The names, or tags, of Mona and Mos have been scrawled over a five mile radius of the town.

Two officers in Dartford have been spearheading a campaign to catch vandals who daub their tags over walls, buildings and other structures.

Pcs Stephen Dingwall and Dave Houlding visit schools and colleges to try to identify graffiti tags and images.

They are absolutely everywhere, either written in silver or in black Pc Stephen Dingwall

Pc Dingwall said they often find the tags written in the back of exercise or homework books.

So far two teenagers have been arrested as a result of the crackdown

The 15-year-olds have been released on bail pending further enquiries.

But Pc Dingwall said they are still anxious to find the culprits behind the Mona and Mos tags.

Links investigated

He said: "They are absolutely everywhere, either written in silver or in black."

"We are taking this matter very seriously as this kind of crime affects the whole community."

Offenders may also be told to clean up the mess themselves.

Pc Houlding said: "We are working closely with the probation service which organises the clean-up of graffiti using offenders who have been given community service orders."

The two officers are also working with the Metropolitan Police and British Transport Police to investigate links with incidents from outside north Kent.
