A prisoner whose case was made into the US documentary 'Making a Murderer' has had his conviction overturned.

Brendan Dassey confessed to helping his uncle carry out the rape and murder of a 25-year-old woman in 2005 - when he was 16 - but his lawyers said his confession was coerced.

A court in Wisconsin has ordered the 26-year-old to be freed within 90 days unless an appeal is lodged.
