A £10,000 reward has been offered to trace the killer of a DJ who was stabbed to death in his elderly mother's flat.
Luke Jackson, 33, was found dead in Pimlico two years ago on Monday.
He died in front of his mother after two men stabbed him repeatedly in the chest with an eight-inch kitchen knife.
Police released CCTV footage on Monday of two men seen walking away from the area who they want to speak to.
Mr Jackson, who co-hosted a weekly online music radio show, was able to “manhandle” the attackers out of the flat before collapsing.
His mother Elizabeth Jackson was arrested in connection with the murder in December 2014 but released without charge.
Two men were arrested in December 2014 on suspicion of murder but were both released without charge.
Nobody has been charged with his murder and the knife used has never been found.
Coroner Dr Fiona Wilcox recorded a verdict of unlawful killing.
Crimestoppers has now offered a £10,000 reward for anyone with information in a bid to find Mr Jackson's killers.
