Exclusive: Uzo Mbonu describes being targeted and completely isolated' by colleagues at HMP Swaleside

A black former prison officer has said he suffers flashbacks and nightmares after colleagues in a high-security jail subjected him to extreme racist abuse and managers failed to support him.

Nigerian-born Uzo Mbonu said he felt he was picked on and ostracised by other officers at HMP Swaleside in Kent because he did not have a British accent, did not understand the jokes his colleagues made, and challenged things he felt were going wrong.
