A father is the sole survivor of a house fire that killed his wife and five children.

On 15 October 2012, Dr Abdul Shakoor jumped from an upstairs window of his house in Harlow, Essex. It was a desperate attempt to get help.

His wife Dr Sabah Usmani and their five children died in the fire and police opened a murder investigation.

Dr Shakoor has been fighting for answers and justice ever since.
