A teenage boy and a woman have died days after a fire ravaged their south London flat which investigators believe was started deliberately.
The blaze, in Russett Way, Lewisham, on Saturday morning had already killed a five-year-old boy, with all three from the same family.
Tributes have been placed at the scene.
The 14-year-old died boy yesterday, while the woman, 34, passed away today, both having sustained serious injuries, the Metropolitan Police said.
Their relatives have been informed and are being supported by specialist officers.
A post-mortem examination on the five-year-old gave his cause of death as inhalation of fire fumes.
Detectives believe the fire was started deliberately but are not looking for anybody else in relation to the investigation.
Firefighters in breathing apparatus were able to pull all three occupants from the blaze in the top floor split-level maisonette and they were taken to hospital via ambulance.
