RTÉ News has learnt that An Garda Siochána is to conduct an internal investigation in the circumstances of the arrest of a man who had taken legal action against the gardaí.
Pat Rossiter is the father of Brian Rossiter, who died while in Garda custody in Clonmel, Co Tippeary.
Mr Rossiter was arrested on a public order charge last year after he had indicated his intention to sue An Garda Siochána for the wrongful death of his son.
Last week that charge was dismissed in Clonmel District Court.
