A man has been arrested in England in connection with the murder 14 years ago of Belfast solicitor, Pat Finucane.
Detectives from the Stevens Inquiry investigating alleged collusion, accompanied by PSNI officers and local (Sussex) police, arrested the 45-year-old at an address in Sussex. A 45-year-old woman was also arrested.
The man has been taken to the North for further questioning and the woman is being questioned by Sussex police.
Mr Finucane's murder was one of the most controversial killings during the troubles.
The well-known Catholic solicitor was shot dead by the Ulster Freedom Fighters, a cover name for the UDA, in front of his family at his home in North Belfast in February 1989.
According to some reports, the man being held is Ken Barrett. Mr Barrett was secretly filmed by the BBC Panorama programme as he discussed how collusion between elements in the security forces in the North and Loyalist paramilitaries had resulted in the murder of Mr Finucane.
Last month, a report by the Metropolitan Police Commissioner Sir John Stevens revealed that rogue elements within the police and British Army in the North helped Loyalist paramilitaries to murder Catholics in the late 1980s.
The Stevens 3 report also found that military intelligence in Northern Ireland helped to prolong the troubles and that informants and agents were allowed to operate without effective control and to participate in terrorist crimes.
