POLICE are hunting a mystery stalker who has bombarded a woman with chilling cards — and signed them off as "your rapist".

Detectives are trying to track down the pest after a six-year harassment campaign in Bristol.

Often giving the name "Gordon", the cards have become more graphic and now contain threats to stalk and rape.

The victim, in her 40s, pleaded: "Someone out there must know who it is."

She went to the police in January last year after the stalking threats got more severe.

Now officers are hoping other victims might come forward to help ID the creep — who often sends animal-themed cards.

Whoever is writing the cards uses distinct handwriting and marks the notes with five kisses.

Cops believe the cards are being sent in the Bristol area and are appealing for help from the public.

DC Patrick Prescott of Avon and Somerset Police said: "We’re releasing extracts of the offender’s handwriting and signature as we believe someone will recognise the style and know who the sender is.

“Do you recognise this handwriting, the name Gordon or the signature with the five crosses? Do you know who may be sending these cards?

“If you work in a shop which sells cards, or if you work in the postal service, do you recognise the handwriting or the distinctive pattern of crosses?

“The content is becoming increasingly sexually explicit and aggressive in nature and includes threats to commit rape and stalking offences.

“We’ve been working with a criminal profiler at the National Crime Agency to examine and risk-assess the offender’s behaviour and are continuing to progress numerous lines of enquiry.

He added: "You may recognise one or more of the characteristics but can’t believe the person you have in mind would commit offences like this. It could be a colleague, friend or even a family member.

"We’d ask you to please report any concerns or suspicions to help us make this stop."

The victim said: "This has been going on for so long - someone out there must know who it is.

“Whether it's the distinctive crosses, the handwriting or the name they call themselves, if you recognise anything that could help the police, please let them know.”
