“Detectives have spent the day gathering footage from nearby doorbell cameras and other CCTV. The scene of the fire has undergone extensive forensic examination to help us understand how the fire started.

“I would ask anyone in the area who saw any activity on Sunday evening around 6.45pm in Glenister Park Road, between Drakewood Road and Streatham Vale, or has information about the incident, to come forward immediately.

“We understand that such a tragic incident will cause concern among the wider community, however we believe that this is an isolated incident and we have arranged for additional patrols in the area over the coming days to help provide reassurance.”

A post-mortem examination has yet to take place.
