A highly venomous green mamba snake that escaped from its presumed owner on Tuesday after biting her in the Czech capital, Prague, has been caught. The snake had gone into hiding in a Prague district and residents were placed on alert and warned to keep an eye out for the reptile. The woman, who had not registered the snake, is in an induced coma at a city hospital after receiving an antidote. The snake was caught in a tree near its home on Friday.
