Eight lions from a pride that featured in the BBC TV series Big Cat Diary have been poisoned in the Maasai Mara in Kenya.
The lions from the Marsh Pride appear to have eaten the carcass of a cow laced with poison on Sunday. A lioness known as Bibi - a favourite among viewers of Big Cat Diary - is reported to have died after being discovered foaming at the mouth and panting frantically.
Kenyan authorities have arrested three Maasai herdsmen after the lions killed two of their cows. A fourth suspect is still at large, said Moses Kuyioni, the reserve's chief warden. If convicted, they face a maximum fine of 20 million Kenyan shillings ($295,700) or life imprisonment.
The Maasai Mara National Reserve is surrounded on three sides by an increasing population of herders and villagers who are desperate for land. Every night, thousands of cattle are driven into the reserve for grazing. Lions often hunt these animals - and Maasai herders retaliate by poisoning the predators.
Brian Jackman, a safari expert with Telegraph Travel, named the stricken pride when he co-wrote the book The Marsh Lions, which inspired the BBC series.
