White tiger mauls zookeeper to death in Japan
Police are investigating the incident after 40-year-old Akira Furusho was found unconscious and covered in blood in the tiger enclosure at the Hirakawa Zoo, Kagoshima on Monday.
The tiger named Riku, one of four at the zoo, was tranquilized after the attack but was not put down because Furusho's family did not want it killed.
White tigers are a genetic variant of the more common orange-and-black Bengal tiger but they have black stripes and white fur.
While the zoo was open on Tuesday, the white tiger observation zone was restricted "as police continued to investigate the case," AFP reported.
Riku, who was born at the zoo, is about 1.8 meters in length and weighs 374 pounds, AFP said.
