Five years on from a house fire in Harlow which killed a mother and her five children, police are re-appealing for help to find those who started it.
Dr Abdul Shakoor was the only one of his family who survived when he jumped out of a window to try and find help as the fire engulfed their home in Barn Mead. His wife and children all died.
Police launched a murder investigation but have never been able to find who was responsible.
They're renewing a public appeal to help try and solve the case - which they say is one of the most complex they've ever worked on.
The murder investigation has been one of the most difficult and challenging carried out by Essex Police.
To date more than 70 police officers and staff have worked on the case, nearly 500 people have given witness statements and 1,800 exhibits were collected and stored.
Detectives are now appealing for help with the following lines of enquiry:
- A white man aged in his late teens/early 20s was seen in the area on a bicycle and could be a key witness.
- The family laptop, a black Toshiba Satellite was taken from the house in a burglary. This has not been located.
- The laptop bag and lead were later recovered near to the scene between Whitewaits and St Michael’s Close. Did you see these items being dumped?
- Attached to the laptop lead was a shaver adapter plug. This did not belong to the Shakoor family which suggests someone tried to use the plug.
- Do you know anything about the silver Ford Focus which was set alight?
- In November 2012 a person rang Harlow police station from a phone box and left a message about the fire. Are you that person?
- Also in November 2012 a piece of paper about the murder investigation was left on a shelf in Boots in Harlow. Did you leave that piece of paper?
