Tiger in Florida zoo shot to death after grabbing man's arm and dragging it, zoo says

An eight-year-old Malayan tiger in a Naples, Florida zoo was shot to death after grabbing the arm of a cleaner and dragging it into the tiger's enclosure Wednesday evening, the zoo says.

The man, who is in his twenties, was airlifted to a hospital and was in serious condition, reports CBS Fort Meyers, Florida affiliate WINK-TV.

The Naples Zoo at Caribbean Gardens says it was closed for the day when the man, who works for a third-party cleaning service, "entered an unauthorized area near a tiger that was inside its enclosure. The cleaning company is responsible for cleaning restrooms and the gift shop, not the animal enclosures."
