By Amy Oliver UPDATED: 10:00 EST, 6 June 2012 A 'sexually obsessed' stalker whose explicit texts and phone calls caused a mother six months of torment was the very police officer sent to help her, it has emerged. Dunstable-based Maria Snow, 49, waived her anonymity to speak of her horror at finding out PC Mark Wilkie was behind the daily calls to her mobile. Mrs Snow recalled how former Bedfordshire Police PC would breathe heavily into the phone and tell her how attractive she was to him. The terrifying calls started in August 2009 when Mrs Snow  was going through a difficult divorce from her husband.
