BOGUS water workers struck in Huddersfield twice within an hour - creeping into one couple's home as they had an afternoon nap.
The couple in their 70s woke to find two intruders in their house on Banks Road in Golcar at about 4pm on Friday.
The men claimed to be water workers, but quickly left. They had stolen cash.
An hour later the same thieves are thought to have struck at the home of an elderly man in Lascelles Hall.
The 79-year-old answered a knock on the door at his house on Lascelles Hall Road.
The man outside claimed to be a water worker and tried to talk his way in, claiming they had put blue dye in the water outside and he needed to check the water supply in the property.
The victim refused to let him in, but the man's accomplice had already slipped in through the unlocked back door and searched drawers and cupboards. It is not clear what was stolen.
The conman at the door was white, aged 16 to 18 and 5ft 8ins with a ruddy complexion and short, light brown hair.
He wore a light- coloured jacket, shirt and trousers and white trainers.
His accomplice, who was seen at the Golcar burglary, is white, aged 20 to 30 and had an Irish accent. He wore a dark top and dark trousers.
