Following an earlier public appeal, Raynolph Asante, 22, of Pembury Road, Travis Mitchell, of Bodney Road, and Rhamyah Bailey-Edwards, 21, of Williams Avenue in Walthamstow, were charged with murdering Mr Romeo.
Detective Superintendent Kelly Allen, of the Metropolitan Police’s Specialist Crime North, said “This investigation has moved quickly with officers arresting four men within five days.
Following Mr Romeo’s death, officers in Hackney have deployed additional stop-and-search powers under a section 60 order.
Detective Superintendent Vicky Tunstall, who leads the Central East Command Unit, said: “We understand that the increased police presence in Hackney this week will be concerning for residents.
A family friend of Mr Romeo previously told the Standard he was “vulnerable” and that she had seen him just hours before his death.
