SOPHISTICATED computer software was not enough to mask a former Suffolk teacher's crimes of downloading child porn pictures from the internet.

Suffolk police still managed to track down David Jordan, because although the software wiped the pictures, the title and the web address were left behind.

Jordan, of Teesdale, Carlton Coleville, near Lowestoft, a middle school teacher who formerly taught design and technology, pleaded guilty to five charges of making indecent photos of children.

Judge John Devaux heard at Ipswich Crown Court yesterday how Jordan was experienced in IT .

Prosecuting Robert Sadd told how police had managed to track down images that 37-year-old Jordan had been looking at, despite the software automatically shredding or wiping it once it had been downloaded.

He said: "There was a flaw in the software.

"It left behind the title and an address and also the size of the picture.

"Using these two pieces of information the police were able to go back on the internet and find an image with the same details of the same size."

Although some of the exact images could not be found the titles Mr Sadd said the titles were clearly related to child porn.

One image that was found showed a young girl and boy engaged in sexual activity.

Judge John Devaux ordered that Jordan should sign the sex offenders register.

His sentencing was adjourned for pre-sentence reports to be carried out.

Jordan was released on unconditional bail.
