Sussex Police: Brighton attack man died of heart disease
A man who was attacked in his Brighton home and was at the centre of a murder inquiry died of heart disease, a post-mortem examination has shown.
Christopher McLean answered the door on 6 January to two men who attacked him in his flat in Caledonian Crescent.
Sussex Police launched a murder probe after the 65-year-old man died.
Officers said on Tuesday they were still treating the incident as a major crime. Police have appealed to the two men to come forward.
Det Ch Insp Nick May said: "I am appealing directly to these two men to contact us.
"Come forward, tell us what you were doing at Mr McLean's flat and what happened. We can then establish the circumstances of Mr McLean's death."
Fight broke out
Police said Mr McLean, who was known as Mac, answered the door to the suspects between 20:00 GMT and 20:30 GMT.
The men confronted him, barged into his flat in Caledonian Court and a fight broke out, police said.
Officers said it was possible Mr McLean knew the men and the motive for the attack was being investigated.
After the incident, Mr McLean began to feel unwell and his partner called an ambulance, but he later died.
Police said a post-mortem examination had revealed Mr McLean died of coronary heart disease, but further tests were being carried out to establish the link between the incident and his death.
One of the men was described as white and about 5ft 4in (1.6m). The other was described as white, about 5ft 6in (1.7m), with a stocky build and aged in his late 30s.
Anyone with information is urged to contact detectives.
