"There have been no escapes. Please don't believe the rumours. All our crocs are accounted for. #safe #rumours," tweeted the trust, assuring that its staff was working round the clock to watch the animals.

The Chennai zoo is flooded, apparently for the first time ever. Officials were forced to walk four km to reach it. Heavy rain has damaged a 40-year-old wall around the zoo but officials said all animals are safe.
There are over 150 animals in the zoo, including 46 endangered species. Officials denied that animals were out of their cages because of the flooding.
