Passage Ten
Toronto: A 300-pound adult Siberian tiger escaped from its four-meter high chain-link-pen at the Toronto Zoo yesterday, on one of the busiest days of the year.
Though no one was hurt, the dangerous animal was separated from the public for a time by nothing more than a four-foot fence. The escape occurred after one of the animal’s handlers left the pen gate open. It prompted a swift response from officials. Staff were sent immediately to arrest the runaway tiger.
General Manager Calvin White told reporters that staff were preparing for the worst. “I ordered a tranquilizer (麻醉剂) gun so we would have tranquilized her, but thankfully we didn’t have to,” Mr. White said. The tiger was successfully led back into its cage after the brief escape.
