Loyalist paramilitary killer Michael Stone has been released, a police spokeswoman said tonight.
She said a file would be sent to the Public Prosecution Service (PPS).
Stone (50) was questioned in relation to terrorist offences in Antrim, after voluntarily walking into a police station in London on Tuesday. He was flown to Belfast accompanied by detectives from the Police Service of Northern Ireland after his arrest..
Stone shot dead three mourners at an IRA funeral at Milltown Cemetery, Belfast, in 1988. He served part of a life sentence for the murders at Milltown when he fired shots and threw hand grenades into a crowd of mourners attending the funerals of three IRA members shot dead by the SAS in Gibraltar.
He was released early in June 2000 under the terms of the Belfast Agreement, but later distanced himself from from ex-associates because of tensions inside the Ulster Defence Association.
He has been questioned a number of times in the past by police after surrendering himself in Northern Ireland, but has never faced any new charges.
