An Indian billionaire's son has offered to help Colombia get rid of a problem it has grappled with for years - a herd of hippos linked to notorious drug lord Pablo Escobar.
Escobar, who was shot dead by police in 1993, illegally imported exotic animals, including a male and a female hippopotamus - dubbed the "cocaine hippos".
Their population grew and Colombia tried various methods of control - including castration - to no avail. It has decided to cull some 80 of the animals.
Anant Ambani - son of Asia's richest man Mukesh Ambani - says he is "willing to receive and care for" the animals at his private Vantara zoo in India's Gujarat state. Colombia has not commented on the offer.
In a letter to Colombia's environment minister, the CEO of Ambani's zoo said they were ready to give the herd "lifelong care" in India.
