Reward over London charity worker's murder
Police have offered a £20,000 reward for information three years after the murder of a human rights worker in south-east London.
Abdel Salam Hassan Abdel Salam, 56, was found by neighbours at his home in Lee on 13 March 2010. He had been stabbed in the leg and died of blood loss.
The victim volunteered at the Redress charity, a human rights organisation which supports survivors of torture.
Police say people in the local community may hold the key to the case.
Officers are offering the reward for information which leads to a prosecution.
Det Ch Insp Graeme Gwyn said: "It has now been three years since the murder of Abdel Salam.
"We have always believed the answer to this crime lies within the local community and someone out there has information that could greatly assist our enquiries.
"Please come forward."
He would often travel by minicab or bus to the charity where he volunteered in central London.
He was found after a neighbour noticed his front door open in Boone Street, Lewisham.
The ambulance service attended but Mr Abdel Salam was pronounced dead at the scene.
Police say they have carried out "extensive" inquiries over the last three years.
An appeal has been made on Crimewatch.
