Detectives are hunting a gang of crooks dressed in onesies who robbed a McDonald's outlet.
The raid happened at a fast food chain in Glinton, Cambridgeshire.
Two men dressed in camouflage onesies - items of all-in-one leisure wear which have become popular with adults in recent years - and another in a navy gilet with a grey hooded top were caught on CCTV threatening staff and demanding money. They were all wearing balaclavas.
No one was injured but staff were left shaken, Cambridgeshire Police said.
Detective Constable Audrey Campbell said: "There were a number of people in the area at the time of the incident and I would urge anyone who witnessed the robbery to get in touch.
"I'm also keen to hear from anyone who recognises the three men or have any information about the clothing they wore."
The incident happened just before midnight on December 22.
