The 52-year-old zookeeper, identified only by his surname, Shim, had been in critical condition at Ajou University hospital in Suwon, south of Seoul since the 3-year-old tiger bit him on the neck and back after it escaped from its cage Nov. 24.
The tiger was returned to its cage before it reached any visitors, and no one else was injured, Yonhap News Agency reported.
The incident prompted calls for improved safety checks and awareness at the zoo, the South Korean news agency said.
