Colm Murphy, from Ravensdale, Co Louth, has been the only person convicted in connection with the bombing. He was sentenced to 14 years' imprisonment in January.
Rachel Donnelly, in London, adds: Anti-terrorist police in Leeds were questioning two men yesterday in connection with bomb attacks in London and Birmingham believed to have been carried out by the "Real IRA".
The men, aged 42 and 43, were arrested during early-morning raids at addresses in Nottingham and Gloucestershire and taken to a police station in Leeds for questioning about suspected "Real IRA" bomb attacks in Britain in the past two years. Both were arrested under the Terrorism Act 2000 and can be held without charge for up to seven days.
The arrests follow several bomb attacks in Britain. The most recent incident was on November 3rd last year when a car bomb partially detonated in a city centre street in Birmingham, but no one was injured. On August 3rd last year a car bomb exploded in a busy street at Ealing Broadway, in west London.
