The PSNI has refused to reveal if it intends to quiz the former Libyan foreign minister who defected to Britain about his country’s role in IRA arms shipments.
Moussa Koussa arrived at Farnborough Airport on a private jet from Libya on Wednesday.
Last night it emerged that Protestant victims’ group Families Acting for Innocent Relatives (Fair) has written to the Prime Minister asking that Mr Koussa be handed over to the PSNI.
Lagan Valley MP Jeffrey Donaldson also called on the PSNI to question the ex-Libyan minister.
Mr Koussa led the Libyan intelligence agency from 1994 to 2009. He is currently being questioned by security officials.
Mr Donaldson said: “I think that there’s an opportunity to question him about Libya’s past involvement in arming the IRA and supplying them with other support. His time as foreign minister came after the main shipments, but he may have acquired knowledge as to what went on.”
Mr Donaldson has fronted a campaigned for victims of IRA violence to get compensation from Libya.
The supply of thousands of tonnes of arms and explosives, including Semtex, to the IRA by the Libyan government is believed to have started in the early 1970s and continued until the mid 1980s.
Fair campaigner Willie Frazer is demanding Mr Koussa be handed over to the PSNI.
He said: “This man just can’t be flown in, put up for six months, and then we get up one morning to find out he’s gone away.
“Everybody talks about closure and moving on.
“They have an opportunity handed to them so we can get closure and move on.”
A PSNI spokesman said: “We are not making any comment at this stage. No inference should be taken from this.”
During the 1970s and 1980s Libya supplied thousands of tonnes of arms and explosives to the IRA. In recent years the victims of IRA violence have campaigned for compensation from the Libyan authorities. The defection of the former Libyan minister Moussa Koussa has sparked calls for him to be questioned by the PSNI.
