A US zookeeper died Friday after she was mauled by one of the tigers in her care, news reports said.
The 38-year-old was inside the animal's enclosure preparing for a tiger show at the Palm Beach Zoo in Florida when she was attacked, broadcaster WSVN said, quoting a zoo spokesman.
The Malayan tiger was not in an exhibit area where guests could see it when it attacked keeper Stacey Konwiser, the spokesman said.
"No guests or visitors were ever in jeopardy," zoo spokesman Naki Carter told WSVN. As a precaution some patrons of the zoo were told to secure themselves in a gift shop.
Local police had to wait for a tranquilizer to take effect on the tiger before they could approach the injured zookeeper.
Konwiser, the primary tiger keeper at the zoo, had always had a passion for tigers, and zoo officials did not know what made the animal attack, according to WSVN.
The zoo was closed until further notice. An investigation was under way.
The tiger was one of the zoo's four Malayan tigers, which are considered critically endangered.
