Paddy Hill, who was wrongly convicted and jailed as part of the 'Birmingham Six', has died.
He passed away at home on Monday morning at the age of 80.
He was one of six men from Northern Ireland who were jailed for life in 1975 after they were wrongly accused of involvement in the Birmingham pub bombings the previous year.
Some 21 people were killed in explosions at two Birmingham city centre pubs in November 1974.
The Birmingham Six spent almost two decades in prison for the bombings before their convictions were quashed in 1991.
The six men were later awarded financial compensation ranging from €1.014 million to €1.449 million.
Following his release from prison in 1991, Paddy Hill set up the Miscarriages of Justice Organisation to support others who had been wrongly accused of crimes.
The Miscarriages of Justice Organisation (MOJO) said in a post on their Facebook page that Mr Hill died peacefully at home on Monday morning.
They said: “It is with great sorrow Paddy died this morning peacefully at home. Our condolences to his family at this sad time.
“We ask that you respect the family’s privacy.”
