Face of Nation : Steven Narvaez-Jara was killed at a flat in Bartholomew Court, Islington, in the early hours of 1 January 2018.
The 20-year-old, from Belvedere, which straddles London and Kent, was found suffering stab wounds and died at the scene, with another man, also 20, later recovering from similar injuries.
Daniel Previous Lena, 19, of Staveley Close, Hackney, and Ramani Boreland, 20, of Ambleside Close, Hackney, were arrested in the days after the murder.
Mohammed Musse, 20, of Spotter House, Berger Road, Hackney, was arrested on the day.
All three suspects were bailed after being released under investigation last November, but police issued them with charges via postal requisition on 6 July.
Police are continuing to investigate the murder, which was one of four in the space of just a few days spanning a series of unrelated violent incidents in the capital over the New Year period.
