More than 30 people in the UK have been arrested on suspicion of accessing US-based paedophile Web sites.

Officers from 30 forces took part in the raids, which were coordinated by the National Criminal Intelligence Service (NCIS).

They were tipped off by US authorities, which passed on details of people suspected of subscribing to paedophile Web sites between May 1999 and summer of 2001.

Some of those sites contained images of children as young as five, according to the BBC.

No one from NCIS was available for comment at the time of writing.

Last month British police carried out a series of dawn raids in what was regarded at the time as the UK's biggest crackdown on Internet paedophiles.

Twenty-seven people, including teachers and those from the medical profession, were held following raids by officers from 34 forces.

Several people were arrested - the youngest just 15 years old. ®
