Police investigating the death of a World War Two veteran after he was robbed have released CCTV images in a renewed appeal to find his attackers.
Peter Gouldstone, 98, was found with bruising and a head injury at a house in Evesham Road in Bounds Green, north London, on 5 November 2018.
He died in hospital weeks later after suffering two bleeds on the brain.
Homicide detectives are appealing for information about an attempted burglary at another home on the same night.
CCTV images show two men entered the back garden of a property at about 20:30 GMT.
The men can be seen looking through windows and attempting to open doors before leaving the scene.
The Metropolitan Police said it was "very keen" to speak to at least three men believed to have been involved in the attempted burglary.
Det Insp Alison Cole added: "We are appealing for anyone who thinks they may know these individuals to get in touch with any information, no matter how small."
"Mr Gouldstone tragically died following a senseless attack in his own home and we are doing all we can to help his family get the justice they deserve," she added.
A post-mortem examination was held on 10 December but the cause of death is yet to be established.
A 26-year-old man arrested in December on suspicion of murder remains under investigation.
A second man, also in his mid-20s, was arrested on suspicion of murder in January and has since been released under investigation.
