British police are continuing to question a man arrested in Northern Ireland in connection with a series of suspected "Real IRA" bomb blasts.
The 24-year-old was arrested on Saturday over the explosions at Birmingham, Ealing and outside the BBC last year. A Scotland Yard spokesman said he was taken to a central London police station where he remains in custody.
A second man (36), also arrested on Saturday under the Terrorism Act 2000, has been released from custody in the North.
Both arrests were made by Police Service of Northern Ireland at the request of the Metropolitan Police's Anti-Terrorist Branch.
On March 3rd, 2001, a car exploded outside BBC Television Centre in Shepherd's Bush, west London, slightly injuring an Underground worker.
Five months later, on August 3rd, another car blew up in a street in Ealing, west London, injuring 11 people. On November 3rd, a car bomb near the Bull Ring in Birmingham did not detonate properly.
