Former Wellesbourne Primary School teacher Daniel Kinge, 28, was jailed for 12 months at Worcester Crown Court last week after admitting downloading 424 indecent images of children.

He had been jailed for nine months in 2005 for downloading pornographic images of children, some of which were kept on school laptops.

And it has emerged that the disgraced teacher, of Cheltenham, Gloucestershire, had since set up websites for teachers after changing his name.

Kinge reinvented himself after posting a message on his own Friends Reunited site in 2006 saying "Daniel Kinge died on November 18," thought to be a reference to the date of his arrest 2004 at Wellesbourne Primary School, where he worked as a reception teacher.

He changed his name by deed poll to "Samuel Kinge", leaving him free to launch and run a widely-used teachers' resource website giving him access to primary schools.

He went on to build up the website for three years before being caught again for paedophile offences.

The site, SparkleBox, is used by teachers all over the world and gives advice on planning lessons and keeping children entertained.

It was blocked by many local authorities after it was discovered Kinge had been arrested for a second time, and teachers and headteachers were warned to stop using the site.

Ian Baker of Wiltshire Council said in a letter: "It is understood that a person who is on the record as an owner and director of Sparklebox Teacher Resources Limited is a registered sex offender who has recently admitted a second offence.

"In the circumstances the trust will continue to block sparklebox.co.uk until they are satisfied that suitable safeguarding arrangements have been made."
