'Robin Hood' gang rob gourmet stores to feed Hamburg's poor.

They dress up in pink catsuits, have names like "Spider Mum" and feel a social obligation to plunder the most expensive restaurants and gourmet delicatessens in town as part of a campaign to help the poor.

The gang members seemingly take delight in injecting humour into their raids, which rely on sheer numbers and the confusion caused by their presence. After they plundered Kobe beef fillets, champagne and smoked salmon from a gourmet store on the exclusive Elbastrasse, gang members thrust a bouquet of flowers into the hands of a shop assistant. Attached was a handwritten note which proclaimed: “Survival in the city of millionaires would be impossible without us!” It was signed by “Spider Mum”, “Santa Guevara” and “Multiflex”.

The latest robbery is part of a pattern over the past several months, suggesting that the thieves deliberately set out to highlight what they perceive as the inequality inherent in German society.

However, the authorities do not agree. Bodo Franz, a police spokesman, said: "They get off feeling they are just like Robin Hood. There are about 30 in the group. But whatever their motives, they are thieves, plain and simple."

Last week the well-heeled citizens of Hamburg's Altona district got a taste of their antics when 30 of them marched into the city's luxury "Fresh Paradise Goedeken" supermarket and walked out five minutes later with £10,000 worth of stolen goods.
