A cyber-stalker who conducted a campaign against a young woman by setting up a website which invited strangers to rape and abuse her was yesterday jailed for seven-and-a-half years.

Donald Ridley, 37, from Poole, Dorset, pleaded guilty to 25 offences relating to "internet stalking" and child pornography at Bournemouth crown court.

The court heard how Ridley, who had met the woman six years ago, sent her a Valen tine's card when she was 17. At one point his victim was receiving around 30 emails a day from people who had seen the website, and a number even turned up at her home, the court heard.

Detective Constable Rupert Evernden, from Dorset police's vice squad, said: "The victim started getting emails from people trying to contact her - that is how we first became aware of it."

Ridley was finally caught after officers raided his home as part of a separate investigation into child pornography.
