The man, believed to be aged 20, was taken to hospital where he was pronounced dead over an hour later.

Next of kin have been informed.

Formal identification and a post-mortem examination will be arranged in due course.

An incident room has opened at Lewisham under Detective Chief Inspector Rebecca Reeves of the Homicide and Major Crime Command.

Detective Chief Inspector Rebecca Reeves, said:

Although we are in the early stages of the investigation we believe that an argument involving a number of men and women took place in Tower Bridge Road. This then continued in Queen Elizabeth Street where the victim subsequently died.

The area around Tooley Street has a popular nightlife and I would ask that anyone who had been to a club in the area and may have witnessed the assault to contact us.

A number of night buses also use this route and it is possible that someone travelling to work, or heading home, may have seen something that will assist our investigation.

Anyone with information is asked to contact the incident room on 020 8721 4868, or Crimestoppers anonymously on 0800 555 111.

Two men have been arrested in connection with the investigation and remain in custody at south London police stations.
