Detectives investigating a house fire which killed six members of the same family have said so far there is no evidence to suggest that an accelerant was used to trigger the blaze.
Essex Police also revealed that the fire appeared to have taken hold in the lounge area which is at the rear of the property.
The ferocity of the blaze has made the forensic work more challenging. Forensic investigations are still underway and is soon to move away from the scene of the fire.
Detective Superintendent Rob Vinson, the Senior Investigating Officer, said:
Police said The forensic work at the address is nearing completion and will now move forward away from the scene.
Experts have found that to date, there is no evidence to suggest that an accelerant was used to trigger the blaze but incident investigators will not be able to draw any final conclusions until the work of the scientists and the investigation is completed.
Police said the mobile police station will remain in Barn Mead for the foreseeable future.
