The explosion tore the walls from the ground floor maisonette in Aldersmead Road on the evening of Sunday 23rd November.
Two men inside the property suffered serious injuries and were later arrested in hospital on suspicion of causing an explosion likely to endanger life. Neighbours escaped unharmed.
Local man Tobias Gordon, 32, suffered burns to his arm, head & back and he died in hospital yesterday morning (2nd December). His family have been informed and a forensic post mortem will be conducted in due course to determine the precise cause of Tobias’ death.
A 27 year old man remains in hospital in a “serious but stable condition” after receiving burns to his back, neck, hands and arms.
Detective Inspector Justin Spanner, from Force CID, said: “We continue to work hard to fully understand what caused the explosion at the flat.
“Local people may be able to help in this on-going investigation and I would ask that anyone who may be able to assist should get in touch.”
The building, a block of 4 maisonettes, has now been demolished.
Anyone with information which may help Det Insp Spanner should call 101. People who do not want to speak with police officers directly can contact the independent charity Crimestoppers anonymously on 0800 555 111.
