From The Irish Echo: BELFAST -- A Derry republican has become the only person ever to spend a day in jail as a result of the shootings on Bloody Sunday - with only Sinn Féin demanding the Northern Secretary, Paul Murphy, release him from Maghaberry prison. Martin Doherty, aged 49, was arrested on foot of a warrant issued after he failed to appear before the Saville Tribunal.
He was named by a British informer as having fired a shot on Bloody Sunday, but he said the evidence is nonsense and he was not present during the shootings.
Before he was arrested, he said: "I am expected to answer allegations made by a man who supposedly saved me during a gun battle I wasn't there for. Later I am supposed to have shot at a helicopter.
"These stories are nonsense. There is more sense in a goldfish and I will treat them with the contempt they deserve. I firmly believe this inquiry is trying to scapegoat the IRA. We all know who murdered the 14 people on Bloody Sunday and it was not the IRA.
