A 13-year-old boy is due to appear in court today charged with a man's murder.
Martin Thomas, 39, died during a break-in and was pronounced dead at his home in Huntingfield Road, Roehampton, south-west London.
The teenager, who cannot be named because of his age, has been remanded in custody to appear at Wimbledon Magistrates' Court today. He was charged with murder on Saturday.
Police continue to appeal for information surrounding the murder on April 22, particularly information that would assist detectives in identifying three people seen in the area prior to the incident.
A post-mortem gave cause of Mr Thomas's death as haemorrhaging due to a stab wound to the lung, police said.
A 15-year-old boy has already appeared in court charged with murder and has been remanded in custody.
A 17-year-old and a 16-year-old both arrested on suspicion of murder have been released on bail.
