When he came round the following morning he felt a sharp pain in his groin - then noticed his genitals had been chopped off, reported local paper STEN.

Police are now investigating the bizarre case, which happened in China.

Tan allegedly told cops he had no idea who was responsible for the cruel prank.

According to the Sanxiang Metropolis Daily, the 44-year-old from Huaihua, Hunan, was bleeding profusely at the time.

Several hospitals apparently turned him away as they were not equipped for such an operation.

Finally, he was taken to Changsha Hospital and treated by microsurgery experts, it's claimed.
