A third person has been charged with murdering a man who died during a break-in.
Martin Thomas, 39, was stabbed at his home in Huntingfield Road, Roehampton, south-west London on April 22.
Odel Munroe, 20, of Sudbury House, Wandsworth High Street, south-west London, will appear at Wimbledon Magistrates' Court today, Scotland Yard said.
Two teenage boys have also been charged with murdering Mr Thomas.
The pair, aged 13 and 15 and who cannot be named because of their age, are both in custody and will appear at the Old Bailey on dates yet to be confirmed, police said.
A post-mortem examination found Mr Thomas died from haemorrhaging after the stabbing punctured his lung.
