Diarmuid Gavin, his obsessed stalker, and the Titchmarsh sting

But for Diarmuid Gavin and his family, it was anything but funny.

The popular television presenter yesterday revealed how he had to enlist the help of Alan Titchmarsh and the BBC to catch the woman after she broke into his home and confronted his pregnant wife telling her: “I’m in love with your husband.”
