A THIEF who has been shoplifting for over 20 YEARS has been caught helping herself to hundreds of pounds worth of merchandise from Marks & Spencer. Kirsty Donnachie, 44, stole clothes and toiletries from the company s store in Port Glasgow just days after appearing in court on other theft charges. Donnachie, of Greenock s Nicolson Street, was also on bail regarding two other shoplifting matters at the time of the offence on September 8 last year. She had been told around a week earlier that she was facing prison after admitting to stealing £22 worth of tea and coffee jars from the town s The Range store.
