In the wake of his abduction on a highway in Tanzania's main city Dar es Salaam, social media activist Edgar Mwakabela, better known as Sativa, says he came close to death.
He describes in an interview with the BBC how, after kidnapping him on 23 June last year, his captors interrogated him and then ferried him across the country to the remote Katavi region near the Congolese border, more than 1,000km (600 miles) away.
Sativa says he was handcuffed, blindfolded and brutally beaten, including being struck repeatedly on his head, back and legs with the flat side of a machete.
"It was extremely painful."
