A number of incidents have taken place in Lancashire with raiders even leaving their wet underwear on the side of the hot tub.
One woman – who had goods including a 42in plasma TV, a Nintendo Wii games console, mobile phones, laptop and a wallet worth more than $5,000 stolen – said the thieves had a lot of “nerve”.
Cherie Deakin said: "It takes some nerve to use the hot tub before breaking in. We have been shocked at how cheeky it is.
"You would expect most burglars would want to get in and out of a house as quickly and quietly as possible, but not these thieves."
