By November 2004, he had been remanded to HMP Brixton to stand trial for another alleged offence, and recorded a verse for Lady Sovereign's "Random" remix over the phone. The case against him was dropped in late December 2004.

Williams appeared on the bonus track "Poltergeist (Remix)" on Roll Deep's 2005 debut album In at the Deep End, As part of Roll Deep, he also appeared on Top of the Pops, providing backing vocals on a 2005 rendition of "The Avenue".

Personal life and artistry Riko raps in what he has described as a "Cockney yardie" style of Jamaican Patois. He enjoyed toasting along to dancehall tapes in his early teens and discovered that he could closely imitate Bounty Killer's tone; his nickname London City Warlord is a variation on Bounty Killer's, The Warlord.
