Police are appealing for witnesses following a distraction burglary in Bletchley.
At about 1.30pm on July 22, an elderly resident discovered a white man with an Irish accent in her home in Tweed Drive.
He told her he was from the water board and he had let himself in with a key and was checking the water pressure.
He then asked her to go into the kitchen and turn on the taps and, while she was doing this, she heard the front door slam.
The elderly woman then discovered items in her bedroom had been moved, although nothing appears to have been stolen. It appears the front door may have been forced open.
Residents are advised to be alert to this type of offence and be wary of anyone unexpectedly calling at the door.
