The inquiry heard yesterday that the account now provided by a soldier about a peripheral incident on Bloody Sunday differs significantly from the statement he made in 1972 about the same incident.
Considerable confusion still surrounds the incident at Bishop Street, just outside the Bogside, where a car carrying a wounded civilian to hospital was stopped at an army road block and a rubber bullet gun - and possibly a pistol - were fired by soldiers.
A witness, Mr Manus Morrison, told how he was a passenger in the car taking Mr Joseph Friel, who had been shot in the chest, towards Altnagelvin hospital when it was stopped at a barrier by two soldiers, one of whom was carrying a baton (rubber bullet) gun and the other, who appeared to be an officer, wearing a side-arm.
Mr Morrison said the soldier with the baton gun told him to get out of the car, and as he was doing so he was suddenly hit at close range by a rubber bullet on his left shoulder.
"He (the soldier) did not say anything to me, he just shot me," said Mr Morrison. "After I was shot with the rubber bullet I spun round and ran. I was very scared. I just wanted to get away." He said he was told later a girl who witnessed the incident at the barrier had said the officer had fired shots after him. He was also told later that the driver of the car, the late Mr James Deehan, had "got a hammering" and spent a couple of days in hospital after the incident.
The inquiry was then shown a statement given to Military Police in 1972 by Soldier 135, of the Royal Anglians, in which he said three cars stopped at the barrier and as he approached the first one a man "threw the door open to block my way".
Soldier 135 said he fired one baton round at this man as he turned to run away, and it hit him a glancing blow on his left shoulder.
Mr Bilal Rawat, a junior counsel to the tribunal, said a more recent statement which Soldier 135 has made to this inquiry says he now remembers only one car at the barrier.
The soldier's account says he went to the front passenger door. There were two men in the front of the car. "I told the driver to turn the engine off . . . and that both men were to f . . . ing get out of the car," the soldier's statement says. "I put my baton gun on the side of the car, resting on the window frame and I immediately fired and blew them out of there.
"The baton round hit them and knocked them both out of the driver's door and on to the ground. They immediately got up and ran away. They vanished down the road."
Another witness, Mrs Pauline Ferry, who was a Knights of Malta volunteer on Bloody Sunday, told of treating one victim, Mr Michael Quinn, for gunshot wounds to the face.
Then she was taken to another house, where a man she was told was Mr Mickey Doherty was lying on a couch with a graze to his leg which she believed was a gunshot wound.
Mr Peter Clarke QC, for a number of soldiers, asked the witness if she had ever heard it mentioned before now that Mickey Doherty might have been a gunman and might have received his injury "on active service against the army". Mrs Ferry said she had not heard this.
The inquiry continues today.
