He and ten members of his 11-man active service unit (ASU) were apprehended attempting to board a flight to Ireland shortly after the bombs were discovered.
Feeney and other members of the group were incarcerated in Brixton Prison, and participated in a 205-day hunger strike[2] with the goal of being transferred closer to their homes in Northern Ireland.
[5] In May 1974, Feeney was one of a group of four prisoners whose transfer out of Brixton was demanded anonymously in exchange for the return of $19.2 million in stolen art.
[6] On 4 June 1974, the IRA kidnapped John Hely-Hutchinson, 7th Earl of Donoughmore and his wife in an unsuccessful attempt to exchange them for the release of Feeney, the Prices, and Gerry Kelly.
[7] During this period he and Brendan Hughes wrote IRA communiqués and articles for Republican News under the pen name "Brownie", although most material published under this pseudonym was written by Gerry Adams.
