Police hunting a stalker who has been harassing a woman for six years have released pictures of several notes in an appeal to people who may recognise the handwriting and distinctive features.
The cards, sent to a 40-year-old woman, have recently become more sexually explicit and include threats to commit rape, Avon and Somerset officers say.
In one, a Valentine’s Day card, the sender ominously signs off: “From your long time secret admirer who has now become your stalker.”
Police say the offences all happened in Bristol and it is believed the cards are being sent from somewhere within the Bristol postmark area.
They are usually signed “Gordon” and always with five crosses – one large X and four small Xs around it.
In a plea to the public, the victim, who has not been named, 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.”
The woman first contacted police in January 2016.
Officers say the cards are always written in capitals and usually feature an animal on the front, often cats.
The force is appealing to anyone who may recognise the handwriting, as well as shop workers and post office staff, to see if any of the distinctive features appear familiar.
Lead officer Detective Constable Patrick Prescott said: “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?
“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.”
Police say they have been working with the National Crime Agency to glean how much of a threat the offender might pose.
DC Prescott said: “Thorough analysis of the communications has been carried out and the possibility the offender has sent, or is sending cards or letters with similar content to other people cannot be excluded.
“If you have been receiving similar correspondence then we want to hear from you.”
Anyone with information should call police on 101, quoting reference number 5216008248.
