A fifth youth has been charged with the murder of gay barman David Morley.
David Morley was attacked on the South Bank
The 37-year-old, from Chiswick, west London, died being badly beaten on the South Bank on 30 October.
The 14-year-old girl from South Norwood, London, is due to appear before Camberwell Green magistrates later on Wednesday.
Four other youths have been charged with the murder of Mr Morley, a survivor of the 1999 Soho nail bombing, who died after rupturing his spleen.
A post-mortem examination revealed he also suffered broken ribs and more than 40 distinct bruises to his head and body.
The accused girl also faces charges of attempted grievous bodily harm (GBH) on two other men, robbery, violent disorder and conspiracy to commit robbery.
The four other youths charged with Mr Morley's murder have already appeared before magistrates this week, and were remanded in custody.
On Tuesday, a 17-year-old, from Kennington, south London, appeared before Camberwell Green magistrates.
He also faces charges of violent disorder, attempted GBH, robbery and conspiracy to commit robbery.
On Monday, Barry Lee, 19, a market trader from Fitzalan Street, Kennington, and two other 16-year-old boys were remanded by the same court.
All four are due to appear at the Old Bailey on 15 November.
Mr Morley was working as a barman at the Admiral Duncan pub in 1999 when nail bomber David Copeland killed three people and injured 73.
