Police have announced that they are offering a £20,000 reward for information on the murder of Terry Isaacs in Brixton.
The reward is available for any information that leads to the identification, arrest and prosecution of the person or people responsible for his murder.
Isaacs, 56, was discovered on Thursday February 19 suffering from multiple head injuries.
Police had been called at 7.44 am in response to reports of a pool of blood in Bannister Close, Brixton.
They searched the area and found Isaacs nearby.
He was taken to hospital by the London Ambulance Service, where he died on Tuesday February 24.
