A giant Aldabra tortoise, second largest in the world and estimated to be worth over ₹ 10 lakh in the international market, has gone missing from the Crocodile Park at Mahabalipuram, 56 km south of Chennai in Tamil Nadu. Though the theft took place six weeks ago at the Madras Crocodile Bank Trust Centre for Herpetology, but seems to have become public only now.
