Polajee “Billy” Rakchongcharoen was last seen on April 17, 2014. At the time the human rights activist was working with lawyers in Bangkok to stop the eviction of Karen indigenous people from Thailand’s Kaeng Krachan National park. For five years his wife fought to solve the mystery of his disappearance, suspecting a cover up by local park authorities. But this summer Billy’s body was found burned and stuffed into a 200-litre oil drum which had been dumped in a reservoir on the outskirts of the national park. BBC Thai’s correspondent, Chaiyot Yongcharoenchai, investigates Billy’s murder and discovers how his death could end up helping the families of other disappeared people in Thailand.

These women became known as the Sew Sisters. Presenter, artist and former Nasa astronaut Nicole Stott meets some of the sew sisters from past and present missions and celebrates their contributions.

New figures released in the UK have revealed at least 4,000 young people are currently caught up in what are known as "county lines" – meeting orders for heroin and cocaine via mobile phone "deal lines". They are transporting drugs from cities to rural and coastal towns, and carrying weapons too – knives, hammers and acid. Many find themselves selling drugs in a strange town, trapped, too scared to leave. Increasingly, when police raid the "traphouses" where the drugs are held, they are finding girls.
