The manager of the Görlitzer Park in Berlin, Cengiz Demirci, said the “pink zones” would help families and other park visitors feel less intimidated by the dealers.

The park’s drug-dealing zones are marked out with pink spray painted boxes.

Mr Demirci told local radio station RBB: “This method has purely practical reasoning behind it. It’s not that we’re legalising the selling of drugs.”

However, the decision came under fire from local police and politicians, The Guardian reports.

Benjamin Jendro from the Berlin branch of the GdP, which represents police officers, said: “What is needed to ensure that the park is drug and crime free is a constant police presence and judicial resolve.”
