Detectives are offering a £20,000 reward for information leading to the arrest and prosecution of two men who murdered an elderly man during a burglary in Tooting.

Mashboor Hussain, 73, collapsed and died following a scuffle with armed burglars on February 11, 2014, at his home in Selkirk Road.

At about 11.45am Mr Hussain opened his front door to be confronted by two men, one of whom was armed with a gun.

The men forced their way into the house and a struggle ensued in the hallway.

Police were called by Mr Hussain's daughter and neighbours who heard a disturbance. On arrival, officers found Mr Hussain collapsed in the hallway.

A postmortem examination attributed to the death to coronary heart disease but the case is being treated as a murder because the disturbance was likely to have caused Mr Hussain’s collapse.

Detective Chief Inspector Graeme Gwynsaid: "It has been more than a year since Mr Hussain's murder and we hope the offer of this large reward will encourage people to come forward with information, no matter how small. I believe there are still people who have yet to speak to us and would urge them to contact us.

"Were you in the area of Selkirk Road at the time? Did you see or hear anything?"

Officers from the Homicide and Major Crime Command will distribute appeal leaflets and speak to people in the Selkirk Road area today.

Anyone who can assist the investigation should call the incident room on 020 8721 4622 or Crimestoppers anonymously on 0800 555 111.
