Tigers are extremely dangerous animals when they are outside the cage.
A tiger escaped from its enclosure in the Cologne Zoo in western Germany, this week and killed a female zoo keeper before being shot dead by a zoo director, police said.
The tiger slipped through a step between the enclosure and adjacent storage building where the tiger fatally attacked a 43-year-old, said police spokesman Stefan Kirchner.
"It seems like that the door was not closed properly," said Kirchner.
The zoo was evacuated and a SWAT team was called in, police said. Before the SWAT team could reach the zoo, the director of the zoo managed to kill the tiger by climbing onto the storage building and shooting the tiger through a skylight with a high caliber rifle.
Police said the tiger was 4 years old.
