Five members of a family have been found guilty over the death of a man whose decapitated body was found in a lake.

Michael Gilbert was kept as a slave and tortured for his benefit money before being killed. His headless body was dumped in the Blue Lagoon in Arlesey, Bedfordshire, last year.

James Watt, his girlfriend Natasha Oldfield, and his brother's girlfriend Nichola Roberts were convicted of Mr Gilbert's murder.

James's brother Robert Watt and his mother Jennifer Smith-Dennis were found guilty of familial homicide following the trial at Luton Crown Court.

A third brother, Richard Watt, had previously admitted familial homicide.

Mr Gilbert's family gasped as the jury returned unanimous verdicts.
