The Brook's Club Bomb Attack occurred on 22 October 1974 on St James's Street in London. The Provisional Irish Republican Army's Active Service Unit nicknamed the "Balcombe Street Gang" threw a 5 lb (2.27 kg) bomb into an empty dining room causing extensive damage and injuring three members of staff of the Brook's gentlemans club. The attacks occurred just two weeks after the ASU began its bombing campaign with the Guildford pub bombings which killed 5, 1 civilian and 4 soldiers and injured over 60 others.
