“I opened it and a picture fell out of the most revolting close-up of what we shall say was a man in a state of excitement, a man’s private parts, and it could not have been a bigger close-up.”And there was an accompanying letter that said: ‘This is for you and there’s plenty more where that came from’ and he even gave his phone number.”Despite leaving the phone number, police were unable to trace the culprit.She added: “I resent his intrusion enormously. You could say he’s done me a favour as I’m incredibly alert because of what could go wrong, and it might sound as if I’m a scaredy-cat or paranoid, but better that than the possibility of a tragic outcome.”It is not the first time Lloyd has spoken of being targeted by stalkers.In 2002, she revealed she had left her London home after eight years after being bombarded with letters and followed by a stranger who even broke into her television studio.Then, she told the Daily Mirror: “This man wrote asking me to meet him for tea at Fortnum & Masons. When I didn’t go, he’d write another letter saying, ‘Well, I know you didn’t turn up last time, so please meet me here.'”It can’t be right that I’ve been forced to move by a stalker. But I feel safer than I have for ages.”A report released this year by the Suzy Lamplugh Trust said only around 26 per cent of stalking is reported to the police, while 43 per cent of those who did make a report found the response not very helpful or not helpful at all.The Violence Against Women and Girls report by the Crown Prosecution Service found the highest-ever number of prosecutions were brought in 2015-16, totalling almost 13,000. “I’ve gone from someone hyper-confident, carefree, going from one thing to another, never looking over my shoulder.
