Tiger in Florida zoo shot to death after grabbing man's arm

An 8-year-old Malayan tiger in a Florida zoo was shot to death after grabbing the arm of a cleaner and pulling it into its enclosure Wednesday evening, officials said. The cleaner, who police say breached a barrier to get close to the animal, was airlifted to a hospital and was in serious condition, according to CBS Fort Myers 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," the zoo said. It is not clear why the man approached the tiger's enclosure.
