Of West African and Irish background, Igbon has been a familiar jobbing actor since his teenage years when he took the background part of inmate Meakin in the 1979 cinematic re-make of the controversial borstal film Scum, whose character memorably launched an emotional tirade against senior members of staff after the suicide of another convict.
Igbon later starred as Loggo in Boys from the Blackstuff, a BBC television drama about a group of unemployed men in Liverpool during the recession-ravaged early 1980s, written by Alan Bleasdale. He also took a leading role in the sitcom The Front Line, playing the dreadlocked Sheldon, alongside Paul Barber as his police officer brother Malcolm, and had a role in the film Water (1985).
Other staple programmes in which Igbon featured include cop show The Professionals, Bleasdale drama G.B.H., medical serial Doctors and Channel 4 soap opera Brookside. He had a supporting role in the third series of Auf Wiedersehen, Pet as a bodyguard and stooge to the programme's main villain (played by Boys from the Blackstuff co-star Michael Angelis) and then took a temporary role in ITV soap Coronation Street, playing the estranged father of regular character Jason Grimshaw.
