Fifteen escapees were captured on the day, including four who were discovered by the RUC hiding underwater in the
river Lagan using reeds to breathe. Escapee

Kevin Barry Artt, Pól Brennan, James J. Smyth and Terrence Kirby, collectively known as the "H-Block 4", were arrested in the United States between 1992 and 1994 and fought lengthy legal battles against extradition.

County Donegal in October 1997 but was not extradited. Dermot McNally, who had been living in the Republic of Ireland and was tracked down in 1996 and Dermot Finucane, received an
amnesty in January 2002, leaving them to return to Northern Ireland. Tony McAllister was not granted a similar amnesty. , Gerard Fryers and Séamus Campbell had not been traced since the escape. ==Mistreatment==
