A visitor at the San Francisco Zoo was killed and twopeople wereinjured bya tiger that escaped fromits cageon Tuesday, according to a report.

The tiger was shot and killed as it attackedthe visitor, Lt. Ken Smith of theCalifornia city'sfire department told the San Francisco Chronicle.

The condition of the two people injured and how thetiger escaped is not yet known.

The attack happened in a café at the east end of the zoo shortly after the 5 p.m. closing time, the Chronicle reported.

The tiger cages are near the centre of the zoo, which was evacuated.

Smith said officials at first worried that four tigers had escaped, but only one got out of its pen.

Last December, one of the zoo's tigers mauled a zookeeper during a regular public feeding. The 350-pound animal reached through the cage's iron bars and badly lacerated her arm.
