An American chef linked to the raid on Special Branch offices at Castlereagh believes he is about to be extradited back to Northern Ireland.
Larry Zaitschek says he fears the Northern Ireland Office will officially lodge extradition papers with the US government later this month.
The 36-year-old has consistently denied involvement in the raid on Special Branch offices at Castlereagh in 2002, which caused major embarrassment to the intelligence services.
But Mr Zaitschek fears he will now be used as a "political pawn" by the intelligence services against the IRA.
"I categorically deny any involvement in what happened at Castlereagh," he said.
"But I am being told the NIO will now seek my extradition before the end of the month."
Mr Zaitschek believes the NIO will take advantage of immigration laws, introduced after the September 11 attacks, to extradite him back to Northern Ireland.
He also said that he fears he will now be used by the intelligence services.
"You have the Northern Bank robbery, Stormontgate and now they will try to bring up Castlereagh again by using me," he said.
Mr Zaitschek said he first heard about the Castlereagh break-in on March 17 2002 when contacted by police.
In the days after the raid he agreed to be questioned twice, be fingerprinted and handed over clothes he had worn on March 17 in the belief it would rule him out of the inquiry.
Mr Zaitschek told police he was returning to New York and supplied them with his address and phone number.
On March 29 2002 Mr Zaitschek was surrounded by FBI officers as he left a New York subway station and was manhandled into a coffee shop.
"They sat me down at a table with two PSNI detectives," he said.
"One of them told me he knew I was involved with the break-in.
"They offered to take me into a witness protection programme and offered me money and all sorts of deals."
Mr Zaitschek said he was further alarmed when he learned his son and estranged wife had been taken into a police witness programme.
"I haven't been allowed to see Pearse in three years and have been blocked from speaking to him since November 2003," he said.
"The police actually said if I told them what they wanted to hear I could speak to Pearse immediately.
"But how can I tell them what I don't know?
"The DPP (Director for Public Prosecutions) has had all the police files for 18 months so why are they now deciding to extradite me.
"The whole thing is a political stunt and if I went back to Northern Ireland now I couldn't get a fair trial because of the lies which have been written about me.
"I am being used as a political pawn and so is my son."
