Two men have been charged with poisoning a pride of lions in Kenya, leaving at least one of them dead.
Members of the Marsh Pride, who live in the Masai Mara reserve and were made famous by the BBC's Big Cat Diary, were believed to have eaten the carcass of a cow which had been poisoned.
One lioness, Bibi, died on Monday morning, with an autopsy revealing the insecticide marketed as Furadan was used to poison the carcass, according to the David Sheldrick Wildlife Trust.
Another lioness, Sienna, has been missing for two days and fears are growing that she too may have died as a result of poisoning.
The alarm was first raised on Sunday morning, when the lions were seen acting strangely.
Experts were called in to inspect and treat them and at least five were thought to have ingested the poison.
Two herdsmen have now been charged in connection with the incident and face prosecution by Kenya's Directorate of Public Prosecutions.
