KATE Winslet has received a string of email deaththreats from a woman stalker. The sinister fan has said she wants to "rape her, kill her and just hit her". Calling herself Dina, she has pledged to visit London soon, saying it is her "only chance" to track down the pregnant Titanic star.

The threats have been left on Kate's fanclub website, kwfc. They originated from the literature department at the Aristotle University of Thessalonica, in Greece, TheMirror has discovered. Last night, no one at the university was available for comment.

"There could be harm for Kate."

Now anything which might give a clue to Kate's address has been removed from the fanclub website. The 24-year-old actress has also been told to stay on the alert. Warnings about the threats were made to Kate's agents more than a week ago in an email headed "Winslet stalker info - urgent!" The message warned Kate's representative, Adam Martin of the London-based agents Peters, Fraser and Dunlop: "There could be harm for Kate."

One message from the obsessed stalker refers to the star's new home in Britain. It reads: "That flat sounds cool...I can get her addy (internet slang for address) then!! hahaaaaaa." This is followed by the internet sign for a smiling face, and the words "Made me day".

Last night Peters, Fraser and Dunlop declined to comment. The firm is sensitive about security issues following the mysterious theft of a computer from its offices. A private investigator has been hired to probe the theft. Police are also involved.

"These days you can't afford to take chances and ignore someone making such threats."

Kate's publicist, New York-based Robert Garlock, also refused to discuss the menace. But a source said: "These days you can't afford to take chances and ignore someone making such threats. Sadly, there are weirdos out there who feel safe using the internet to intimidate and strike fear into their targets. The net allows them to acquire considerable information so they can pursue their own sick ends. Kate is very aware there are people who have an unhealthy interest in what she does and says. That is an unfortunate aspect of her life."

The star's fan club is said to be "seriously concerned" about the threats on its website. However some users of the site are fearful of raising the alarm because they believe it will reflect badly on the club. One wrote: "We don't want to be associated with a sick weirdo or threatening people. If you say 'So and so is threatening', and it's on the kwfc board, that makes an association. It may make them tell Kate to stay away from kwfc people."

Kate is currently at home after finishing work on the movie Enigma, based on Robert Harris's best-selling novel about wartime code-breakers at Bletchley Park. The popular star - married to film director Jim Threapleton, 26 - is expecting her first child in September.

"I try to lead my life as normally as possible, just like Joe Bloggs around the corner."

Two years ago, she told how she was stalked by a 26-year-old man who claimed to be a freelance photographer. She said: "I'd be in the supermarket, and this man would be there. I'd be swimming, and he'd be there. I'd look out of my window, and he'd be there. He was everywhere I turned. It got so that in the mornings I'd open the curtains and he'd be there, sitting in his grey Saab. I'm an actress and don't hide myself away. I haven't barricaded myself behind high fences and security systems. I try to lead my life as normally as possible, just like Joe Bloggs around the corner."

The stalker was arrested under the Protection from Harassment Act and warned to stop hounding Kate. He was then freed without charge.

Britain's first internet stalker was jailed for three months last year. Cambridge graduate Nigel Harris, 24, had already been convicted of harassing ex-girlfriend Claire Dawson, 23, after bombarding her with threatening emails. He then breached a restraining order. The Association of Chief Police Officers said last night: "Stalking on the internet is not seen as a major problem. But, like all electronic crime, it's on the increase."
