PERVERTS downloading vile internet images of children being sexually abused face a new crackdown - with four suspected paedophiles already arrested in raids by cops.

Police swooped on four addresses this week in Flintshire, Denbighshire and Anglesey as part of Operation Tailor, seizing 20 computers, mobile phones, digital storage devices and DVDs.

The raids were triggered by "digital intelligence" after North Wales Police started using new hi-tech software to monitor certain sick internet sites and trap people viewing indecent images.

Police arrested four people and a Denbighshire teenager is due to appear at Prestatyn Magistrates Court today charged with 11 counts of making indecent images of children.

Two men from Deeside and one man from Menai Bridge were released on police bail pending investigation into the seized material. None of the suspects were linked.

Officers warned this was just the start of the fight against North Wales paedophiles using the web.

Hi-tech crime investigator Mike Gallienne said: "People think if they are in their own homes they can't be detected, but now they can be caught anywhere.

"The new digital intelligence which Rolex Replica is now operating means North Wales is a riskier place for paedophiles to access these images.

"If people do not want to be caught they should stop now.

"The images that we come across are vile and involve the abuse of young children. Anyone clicking on and viewing these child abuse images are fuelling these crimes and the abuse of children.

"There is no excuse and we will be pro-active in targeting these people.

"They have to realise the shame and impact they will bring on their own families when they are detected."

The hi-tech crime unit is a six person team of officers with computer expertise who monitor the net for offenders and then investigate computers and other equipment seized.

Mr Gallienne added: "The internet and the increased use of high tech devices like computers and mobiles is creating a new problem for police and is making accessing and sharing abuse images easier, which is why this unit is needed.

"It is a difficult job for staff to do because of the images we find, and we ensure their welfare is screened. They know they are making a difference in cracking down on these people."
