Diarmuid Gavin: Alan Titchmarsh scared off my stalker Gavin, 47, endured months of fear after being pursued by the woman, who followed him to the sets of his gardening programmes and appeared to be "always there." He described one incident in which she attempted to break into his family home and told his wife, Justine: "I'm in love with your husband." Mrs Gavin, the daughter of a former Chief Justice of Ireland, replied, "In that case, you need to see a doctor," and contacted the police, but no further action was taken, he alleged. It is understood the stalking took place in 2004, shortly before the birth of Mr and Mrs Gavin's daughter, Eppie, when the family were living in Harlesden, north-west London. I've had some strange fans over the years but she was a proper stalker and for a long time I was the only one who'd ever seen this woman. She was always there," he said. Diarmuid Gavin with his wife Justine (WENN) "It got so bad I was scared I'd arrive on set one day and someone would say, 'This is your new producer," or I'd go home and find her having tea with my wife. She broke into my house. My wife, Justine, was there and she was pregnant. This woman said to her, 'I'm in love with your husband," and my wife said, 'In that case, you need to see a doctor."" At that point, he said, the couple called the police to investigate but no further action was taken. Gavin added: "It was very hard to get the police to do anything. In the end, the BBC hired a detective and we organised a bit of a sting operation at a flower show. Alan, me and some BBC producers tried to lure her in. She always positioned herself right in front of the camera. Once she was there, we had her. It all died down after that. He said he had not been troubled by the vulnerable woman since. Gavin, who came to widespread attention after appearing on Gardener's World, met Titchmarsh in 1996 when he was interviewed at the Chelsea Flower Show. Since then he has appeared on Home Front in the Garden, This Morning and Diarmuid's Big Adventure. He also competed in the 2004 series of Strictly Come Dancing. At last year's Chelsea Flower Show, he was awarded a gold medal for his "Irish Sky Garden." Speaking of his career, Gavin said: "I always had faith something good would happen, though I never once thought I'd become a TV gardener. That was never on the radar. Gardener's World was never a programme I watched or had any interest in. But when nobody has ever asked you to do something and it's always been such a fight just to be wanted, you're going to go for it. A spokesman for the BBC said it would not comment on security issues.
