Cameroon’s mysterious lake deaths
In 1986, villagers in Cameroon awoke to find hundreds of their friends and neighbours had mysteriously died in the night.
On 21 August 1986, hundreds of villagers in a remote part of Cameroon mysteriously died overnight, along with 3,500 livestock.
In the weeks-long investigation that followed, scientists tried to work out what had happened. How had hundreds died, but hundreds of others survived?
In 2011, scientists Peter Baxter and George Kling told Tim Mansel how they cracked the case.
