RUC Special Branch-linked agent provocateurs tried to incite members of a civil rights group to poison the water supply at an Army barracks in Derry, the Bloody Sunday inquiry was told today.
Hugh Logue said the two showed a map of Ballykelly military base's water system to the North Derry Civil Rights Association, and announced that they had strychnine that could be used in such an operation.
However, Mr Logue said, NCRA members saw through the attempt and did not take the bait.
"We dismissed it out of hand," he said. "We could see it a mile away. It was set up by the security forces to implicate the North Derry CRA in a violent act and we would have no part of it."
Mr Logue added that one of the pair was now dead and he did not know the whereabouts of the other, but agreed to identify them to the tribunal if necessary.
