A new documentary about Robert Nairac has claimed the soldier tracked down a paramilitary suspect in the Republic, against Army rules.

Nairac, who served as a liaison officer between the SAS and RUC Special Branch, was abducted from a pub in south Armagh on May 14, 1977 while working undercover and taken across the border.
