CELEBRITY gardener Diarmuid Gavin enlisted the help of Alan Titchmarsh to launch a sting operation to catch an obsessed stalker after she broke into his home and confronted his then pregnant wife, Justine.
Gavin, 47, endured months of fear after being followed by the crazed fan, who frequently turned up on sets of gardening shows.
But the stalking became more sinister when the woman broke into Dairmuid's home - and told his heavily pregnant wife Justine: "I'm in love with your husband".
Police were called but no further action taken. Horrified BBC bosses then hired a private detective to try and track the stalker down.
Gavin and fellow television gardener Titchmarsh decided to confront the woman and managed to lure her in front of the camera.
Popular television presenter Gavin - who starred in Gardeners' World - said the stalking immediately ceased much to the relief of his terrified family.
He said: "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.
"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.'
"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."
