IT IS broad daylight but with nobody around these taggers think they have got away with spraying their graffiti.

What none of them realised was that all the time they were defacing the walls they were being filmed on secret cameras.

Now the police need your help to identify those responsible.

PC George Booth, of the town centre police, said: "If we find these people we will be dealing with them as severely as possible.

"Because of the public support in tackling graffiti we seem to be experiencing a reduction in the amount taking place in the town.

"Obviously we welcome any further support from the public in relation to apprehending these people."

The first set of pictures were taken on July 4 at about 1.30pm on the steps of Foxies Extreme in Theatre Square.

PC Booth said: "There are two males involved and one female and they have been responsible for writing with marker pens on the steps, which are certainly not artistic in any way.

"There is no discernable tag, only childlike scrawling.

"They appear to be part of a group that were hanging about skateboarding at the time."

The second selection of pictures, taken just after 2pm on July 7, are of two lads on the roof of the Wyvern Theatre car park.

They were part of a group of about five people who went up to level five but it was only these two - the boy in the red top and the other in the black and grey hoody and grey tracksuit bottoms - who were caught on camera.

PC Booth said: "I would say these two are teenagers. They were part of a group that went up but no-one else participated in the graffiti.

"These two have taken part in the same offence. They are obviously friends and it certainly doesn't look like the first time they have used a spray can, judging by the standard, but they may have done it legally until now.

"The tag was a big tag but it's not discernable."

The final set were again taken on the top level of the Wyvern Theatre car park, at 2.30pm on July 14.

PC Booth said: "The lad in the hat has scribbled on a fire door, using no discernable tag while his mate has stood and watched him."

Cheri Wright, the council's anti-social behaviour co-ordinator, said: "As part of the graffiti operation one of the projects was to use covert CCTV in hot-spot areas of graffiti to try and identify who was causing the problems because clearly that's one way of bringing them to justice.

"It's proved particularly successful in catching people, now we need to identify people before arrests can be made."
