When two men strolled into a charity shop, they were welcomed with a warm smile and polite greeting from the volunteer on duty,
But instead of making an anticipated Christmas donation, the pair sprang a sinister surprise.
They pulled out a knife, threatened to use it on the terrified volunteer and demanded cash from the till.
The robbery at Bletchley’s British Heart Foundation shop on Saturday has been described as “abhorrent” by police.
They are appealing for witnesses to help them catch the crooks, who fled the shop with an unspecified amount of cash from the till.
The volunteer was luckily uninjured but is still “very shaken”, say officers.
Detective Inspector Dave Dachtler said: “It appears the victim thought the offenders were making a charitable donation but when she approached the men they threatened her with violence.”
He added: “This offence is abhorrent particularly because it was an incident in which offenders targeted a charity shop.
“Most people who work in establishments such as these give up their free time as volunteers for good causes.”
The robbery happened just before 6pm and police are hoping passing shoppers may have seen the men and call 101 with information.
The first offender is Asian, 5ft 10ins tall, in his early 20s and wore dark trousers with a black quilted jacket.
His accomplice was the same age, slightly shorter and wore red trainers, baggy trousers and a grey hooded top.
