Police want to trace two men who tried to enter the home of an elderly man in Stonehouse, order posing as water board officials.
The 65-year-old victim went to answer a knock at the side door of his bungalow in Sherborne Close at about 9.15am on Friday, August 1, and saw the men at his back gate.
They told him they were from the water board and had come to read his meter and proceeded to walk towards the door, but the victim demanded to see an ID.
When they appeared to ignore him, he challenged them again and they eventually left.
The victim, shaken by the experience, alerted Police. Officers made house-to-house enquiries, conducted patrols locally and checked nearby sheltered housing complexes in case they had also been targeted, but were unable to locate the pair.
The two men are described as being white, aged in their late 30s, about 5ft 10ins tall, stocky and bald. They were wearing blue boilersuits.
Police believe this was an attempted distraction burglary, and that it emphasises the need for people to challenge callers for IDs, which in this case saved the householder from becoming a victim of theft.
Anyone with information which could help the Police enquiry is asked to call 101, quoting incident number 141 of 1/8/14.
