A 72-year-old widow was said to be comfortable but in a state of shock by a hospital spokesperson this morning. Mrs Susan Marsh suffered a head injury during the night when she disturbed an intruder who had broken into her ground floor flat on the Eastfield estate. This was the second time her home had been broken into in a month. In the first raid, the burglar broke a window and climbed in while Mrs Marsh was out for the evening visiting friends. The police believe that on this occasion the thief was disturbed when a neighbour returned home after walking his dog. It is also known that: Following the first break-in, workmen from the Housing Association boarded up the window to Mrs Marshs flat. Mrs Marsh disturbed a man in her living room. When she returned home on the occasion of the first break-in Mrs Marsh found that nothing had been stolen. On the night Mrs Marsh suffered her head injuries the thief escaped with some valuable items of silverware and a small amount of ready cash.
