A paramedic, who was on duty during the events of Bloody Sunday, has given evidence at the Saville Inquiry today.
Charles Glenn, who was 19 at the time, admitted his memory of events may have been clouded by shock but described the abuse he received at the hands of the paratroopers.
Mr Glenn, who had been clearly dressed in his Knights of Malta uniform, also denied throwing stones at British troops.
Mr Glenn said he had no idea what he had been doing between leaving Derry city centre after helping Fr Edward Daly tend to Jack Duddy, the afternoon's first victim, and his arrest a short distance away.
He blamed the shocking experience of seeing a man being shot dead in front of him. "It would certainly be true to say that I was not in a position to take cool, calm and collected views of what was going on around me," he said.
The witness described how he was arrested and brought by taxi to join another group of detainees.
He remembered being assaulted by troops three times during the day and, of the accusation that he was involved in stone-throwing, Mr Glenn said, "It would be grotesque for someone in my position to be throwing stones."
