SINN Féin have declined to comment on claims a man charged in connection with an IRA bomb attack was assured by the party he was no longer wanted by police.
Paul 'Skunner' Campbell was released on bail this week after a judge heard that police had information linking him to a bomb attack at Coalisland police station since 1997 but failed to act on it.
The court had heard that blood found in the back of a priest's car that ferried an injured man from the scene of the explosion was linked to Campbell.
The father-of-three was arrested at a railway station in Portadown, Co Armagh last Sunday in connection with the Provisional IRA bombing.
He was granted bail by Mr Justice Horner who said: "It seems absolutely extraordinary that no steps were taken to detain him" before last week.
The Irish News has learned that the father of three, with an address at The Mills in Coalisland, had been assured by Sinn Féin that as part of the On The Run scheme he was not wanted in connection with the attack
A total of 228 names were but forward to the British government by Sinn Féin as a way of dealing with the issue of 'on the run' republicans.
Between 2000 and 2012, 156 people were sent individual letters of assurance, via Sinn Féin, informing them that they were 'not wanted'.
Mr Campbell returned to Coalisland in late 2001 and worked as a barman in McGirr's pub in the town.
He only became a 'person of interest' after a property connected to him was searched as part of the investigation into the dissident republican murder of Constable Ronan Kerr in 2011.
Solicitor Peter Corrigan of KRW Law told the High Court that his client had been "openly residing in Coalisland" for lengthy periods.
On the night of the grenade attack SAS soldiers opened fire on the suspected bombers, 19-year-old Gareth Doris was injured and was later sentenced to ten years for his role in the attack. He was released after two years under the terms of the Good Friday Agreement.
A second suspect escaped in a Toyota car belonging to local parish priest Fr Seamus Rice amid a hail of bullets. The cleric who is now retired told police at the time he had slowed down upon hearing explosions and a man unknown to him jumped in the back and demanded that he drive off.
The prosecution now claim that blood stains found in Fr Rice's car can be linked to Mr Campbell.
A man calling himself John Murphy was later admitted to a hospital in Co Louth claiming to have been in a road accident. However, medical staff alerted gardai after they realised he had suffered a gunshot wound.
The patient was identified as Mr Campbell and arrested for questioning in the Republic, he was later released and information passed on to the RUC.
Mr Campbell fled across the border again to Co Monaghan in 2011 after police carried out searches of a number of properties as part of an investigation in to a breakaway group of dissident republicans from Co Tyrone.
During last week's bail hearing it was pointed out that Mr Campbell was stopped twice by the PSNI in 2010 in relation to driving matters and was not arrested despite giving his personal details.
He is expected to rely on the assurance he was no longer wanted as part of his defence against the allegations.
Sinn Féin did not comment on the case on Friday, saying they do not hold names of those involved in the scheme.
In February 2014 the case against veteran republican John Downey, charged in connection with the IRA bombing of Hyde Park collapsed after it was revealed he was in obsession of an OTR letter.
