Two men have been arrested after a man was fatally stabbed as he left work, police have said.
Tobi Animashaun, 25, died in hospital on Monday after an attack in Anchor and Hope Lane, Charlton, the previous evening.
A 23-year-old and a 22-year-old were arrested on suspicion of murder on Friday and remain in police custody, Scotland Yard said.
Police said Mr Animashaun was leaving work through a security gate when he was attacked by a group of men.
He was stabbed in the chest and abdomen, post-mortem examination results showed.
Paying tribute to him, the victim's family said: "Tobi was a son, big brother, cousin and friend. He had a heart of gold and was protective of everyone in his family, especially the girls.
"It truly saddens us that we have lost Tobi but his spirit will live on in our hearts. We do hope the people who are responsible for this are brought to justice."
Detective Chief Inspector Graeme Gwyn said: "Tobi was attacked by a group of males as he left work on Sunday evening.
"We are keeping an open mind as to motive but he was attacked just as he exited the security gate.
"We are keen to speak with anyone with information and ask they contact us as a matter of urgency."
Anyone with information should call police on 020 8721 4805 or Crimestoppers on 0800 555 111.
