The father of the murdered loyalist leader, Billy Wright, said he gave details of the new information he received about his son's murder in the Maze Prison in December 1997 to the North's Security Minister, Mr Adam Ingram.
Mr David Wright, who last week met Mr Ingram and his officials at Stormont to discuss his concerns regarding his son's death, said he expected Mr Ingram "to act immediately and instigate a full, open, public inquiry into this most serious of issues".
Speaking before leaving on a short holiday yesterday, Mr Wright said he contacted Mr Ingram's office on Monday to "make them aware of information I had been given by employees of the Northern Ireland Prison Service". This information clearly showed that his son's murder could have been prevented, he said.
"I have been informed that the wire fencing in H Block 6 had been breached for a number of weeks before Billy was killed," he said. "A prison officer on night duty heard the sound of wire being cut within the exercise yard of A and B wings. The officer reported the matter and it was recorded in the `night guard journal'."
"The matter was also reported to the emergency control room at the Maze. No action was taken by the prison authorities. I am asking Mr Ingram to state publicly who made this decision and why it was taken".
Mr Wright also alleged that at least two prison governors were aware that this breach of security had been recorded. He said he had named the two officials along with other members of the Prison Service in his letter to the minister.
"I have also been informed that the two log books containing details of the security breach have been removed from their normal location within the Maze," he added.
Mr Wright went on to say that this new information also cast serious doubt on the RUC investigation into his son's death.
