Essex Police is to review its investigation into a fire which killed six members of the same family.
Two people arrested on suspicion of murder in connection with the fire at Barn Mead, Harlow have been told they are to face no further action.
Dr Sabah Usmani and her five children, Maheen, Rayyan, Muneeb, Hira and Sohaib Shakoor died in the fire in 2012.

Dr Shakoor jumped from a bedroom window in an attempt to get help, but he was unable to save any of his family.
Investigators have taken hundreds of statements and collected thousands of documents and exhibits as part of the inquiry.
