A murder investigation has been launched following the death of a 30-year-old man.
Police were called to reports of a man assaulted in Tranquil Vale, Blackheath, south-east London, in the early hours of Sunday, Scotland Yard said.
Oliver Dearlove, from nearby Eltham, was taken to an east London hospital, where he died just after 10.20pm.
A post-mortem examination will be carried out at Greenwich Mortuary on Tuesday.
Detective Chief Inspector Lee Watling, of the Homicide and Major Crime Command, said: "We are retaining an open mind at this stage of the investigation with regards to a motive and our primary aim is to establish how Mr Dearlove came to receive the injuries which led to his death.
"We are appealing for anyone who was at Tranquil Vale who witnessed the incident, in particular a group of up to four white females who Mr Dearlove and his friends were speaking to around the time the offence occurred."
No arrests have been made.
