German police said on Monday they were searching for vandals who sprayed the word “Nazis” on the building and vans of a charitable food bank that has stopped accepting new migrant and refugee clients. Essener Tafel charity leader Joerg Sartor said the slogans that defaced a building door and six vans would not immediately be removed because “everyone should see this”. Dismayed by the wider controversy, he also told Bild daily he was considering “throwing it in” and resigning from his post. The charity that serves free meals to the poor had drawn widespread criticism after it declared last week it would from now on demand German identity papers for new clients because a huge migrant influx meant locals in need were going without food. Sartor, 61, said many elderly Germans and single mothers were scared of an increasingly aggressive atmosphere as the number of foreigners using the charity had risen to three-quarters of the total. Sartor said some migrant groups shared a “give-me gene” and did not understand Germany’s “queuing culture”. Germany’s Merkel agrees to cap refugee numbers at 200,000 a year in concession to allies More than 1.2 million refugees and migrants have come to Europe’s biggest economy since 2015 – more than half from war-torn Syria, Iraq and Afghanistan – in a mass wave that sparked a xenophobic backlash. The charity in the city of Essen, like hundreds of similar groups nationwide, collects surplus food that would otherwise be thrown away by supermarkets and serves it to the poor. None of the other more than 900 food banks in Germany publicly said they would follow the move. German police and the internal security service, responsible for investigating politically-inspired offences, said they had launched investigations into the graffiti spraying which occurred at the weekend. France to kick out illegal immigrants who commit crimes The far-right and anti-immigration Alternative for Germany (AfD) party launched a social media campaign in defence of the charity called “If you fight back, you’re a Nazi”. The charity “was not founded to deal with the chaos of [Chancellor Angela] Merkel’s refugee policy but to meet the demand that was already there”, it said on Facebook. Essener Tafel said last week it had taken the step to avoid friction between needy locals and foreigners that could harm acceptance of the newcomers. The charity announced the change locally in December and introduced it January, but it was only widely reported last Thursday, initially by Westdeutsche Allgemeine newspaper.
