Discussions are under way regarding a special tribute to honour hero Thames hero Folajimi Olubunmi-Adewole.
Mr Olubunmi-Adewole lost his life trying to rescue a woman who fell into the Thames from London Bridge just after midnight last Saturday.
The coastguard and the Metropolitan Police marine unit rescued the woman, who is in her late 20s, and another man who had jumped in to rescue her, but Mr Olubunmi-Adewole could not be saved.
The tragedy has led to calls for the Nigerian-born restaurant worker to be honoured for his selflessness and talks are under way for him to be recognised at Postman’s Park.
The garden, close to St Paul’s Cathedral, is home to plaques dedicated to ordinary people who have displayed acts of self-sacrifice.
It was erected by the artist George Frederick Watts and contains tributes from the 1880s to 1931.
On Friday, friends and family of Mr Olubunmi-Adewole gathered at Bermondsey Spa Gardens to hold a vigil in his honour.
His friend Bernard Kosia, told the BBC that he was a "spiritual person” and “his actions say enough.”
“He should be remembered by the whole world," he said.
"I just want to say a thank you to him. Wherever he is right now.”
A spokesperson said: "We feel that is absolutely right to recognise the bravery and selfless actions of Folajimi Olubunmi-Adewole, known as Jimi.
"To honour his memory and heroism, we have contacted the Royal Humane Society to start the nomination process for their bravery award, and we are also looking to award Jimi a commissioner’s commendation from the City of London Police.
"Our thoughts remain with his friends and family at this difficult time."
