Dutton later took to Twitter to claim responsibility and to complain about the treatment he received.

Under the name Operation Fail Safe, he said: “I wear a black SS armband in Asda twice a week for past three years.”

He added: “I got ejected from #ASDA for wearing something that is good enough for a #Prince 2 wear #Asda are a bunch of #Racists.”

He was referring to British Prince Harry, who dressed in a similar Nazi outfit at a costume party in 2005.

Many Cambridge residents didn’t see his costume as a matter of free expression, but as an insult.

Rosina Rusin, 60, from Milton, told the Cambridge News that she felt it was “an affront” that someone would walk around in broad daylight wearing a Nazi uniform.

She said: “I was waiting in a queue when a lady came up and she was really quite distressed about it. People’s mouths were falling open. You are not going to come out like that unless you want to draw attention to yourself.”

Rusin’s mother was of Dutch-Jewish descent she explained to the Cambridge News: “I wanted to make sure he was evicted. My grandmother’s family were annihilated in the gas chambers and I thought here is this bloke parading about.”

Neil Doron, 40, from Cambridge, saw the man outside Asda. He said: “He was just standing there in all that gear. It’s not very nice. At first I thought it was just a guy in costume.”

Doron added: “I do not think people should have that on at any time of year because of what it stands for. It’s not nice for people in Cambridge.”
