FOUR tigers escaped their cages at the San Francisco Zoo yesterday, killing one person and injuring two others, a newspaper reported.
One tiger was shot and the other three were brought under control, San Francisco Fire Chief Audrey Lee told the San Francisco Chronicle. It was not immediately clear how the tigers escaped.
The zoo has been evacuated. It was open in spite of the Christmas holiday, and was scheduled to close at 5pm yesterday (0100 GMT today).
It was unclear whether the victim was a visitor or a zoo worker.
Police officers and firefighters are investigating.
