Four Chelsea fans accused of being involved in a race row in which a black man was shoved off a train while racist chants were sung are being treated as “scapegoats” by police, a court has heard.

A former Northern Ireland policeman who is one of three men sought in relation to an alleged racist incident involving Chelsea football fans on a Paris Metro train, has apologised for his involvement.
