When teachers at Herder school in north Germany discovered a chocolate cake outside their room, they suspected nothing.
Pupils had often brought in cakes to raise money for charity, so staff sliced it up and tucked in.
But before too long, 10 teachers from the elite school in Lüneburg started trembling, feeling unwell and suffering from hallucinations.
Police called in to investigate confirmed that the cake had contained large amounts of hashish.
All 10 teachers were treated at a clinic after eating the cake on Wednesday but were later released. The remains of the cake were being examined, police spokesperson Michael Düker said.
”The cake was left outside the room on Wednesday morning before the break,” the school’s spokesperson, Hans-Christian Höhne, told The Guardian on Thursday night.
”Someone brought it in. A lot of people then had a slice and three-quarters of the cake was eaten. About two or three hours later they all started feeling sick. My colleagues were very afraid.”
The teachers had suspected nothing because for the past six years pupils had been bringing in cakes to support a radioactive measuring station in Chernobyl, he said.
Höhne added: ”It’s impossible to say whether a student or someone from outside was responsible. Either way, it was a bad joke. In future we’ll insist that pupils put their names on cakes.” – Guardian Unlimited Â
