Unreported World exposes the plight of hundreds of children in Burundi locked up for years without trial in adult prisons, among some of the most dangerous criminals in the country. And they meet one man who has dedicated his life to freeing them; Pierre-Claver Mbonimpa is the only hope many of these children have. Burundi has no juvenile justice system and children above the age of 15 are tried as adults. By law any child under that age should not be imprisoned, but in a country recovering from civil war and where record keeping is scant, many underage children are slipping through the net and are being locked up.
