Death-row inmate Celestine Egbunuche has been dubbed Nigeria's "oldest prisoner" amid a campaign calling for his release.
He is 100 years old and has spent 18 years in jail after being found guilty of organising a murder.
Small and slightly hunched over, he looks wistfully into space as he sits on a tightly packed bench inside a stuffy prison visitor's room.
Dressed in a white T-shirt, shorts and flip-flops, he lifts his head slowly - his way of acknowledging our presence.
But otherwise he remains quiet during our visit - in stark contrast to the rest of the room that is filled with loud chatter at Enugu Maximum Security Prison in south-east Nigeria.
