"A former detective has said the RUC team investigating the bombing would have had no involvement in any decision not to question XXXXXXXXX.
"The retired detective, who did not want his name used but who was close to the investigation, said the decision to leave the priest alone was made at a senior level.
"The decision not to pursue XXXXXXX was not taken at a low level, it was not made by those who were investigating this or were any way associated with it," he told the BBC on Wednesday.
"This was not a decision by the RUC in general, this was not a decision by the detective inspector who was leading the investigation and those who were working with him.
"This was a decision made above - way above - the investigating team."
