Murder investigation launched in Brighton Police were called to a flat in Stafford Road at 1.58am on Wednesday (September 11) after a report of a disturbance. Officers forced entry to the premises where they found a man with serious injuries. Two men were detained by police in nearby gardens a short time later having fled from the premises as officers entered. The victim, initially thought to be in his 40s but now estimated to be in his 20s, was pronounced dead at the Royal Sussex County Hospital at 3.53am.. Detective Chief Inspector Alex Geldart, from the Surrey and Sussex Major Crime Team, who is leading the enquiry, said: “We are working with partner agencies in a bid to establish his identity and are undertaking house-to-house enquiries in the area to find out if he was known to neighbours as a resident or may have just been visiting the property. “He is white, appears to be in his 20s, 6ft 2ins and of very slim build. We would like to hear from anyone who may have seen him in the area or who recognises his description. “Please report online or call 101 quoting Operation Barnfield.” Today (September 12), magistrates granted the investigation team another 36 hours to question the men, a 44-year-old from Brighton and a 45-year-old man of no fixed address, who have been arrested on suspicion of murder.
