A Spanish national accused of involvement in the 2004 Madrid bombings has been remanded in custody by Bow Street magistrates in London. Moutaz Almallah Dabas, 39, was arrested in Slough, Berkshire, on Saturday and is thought to have been held in a central London police station. He was arrested on an extradition warrant from the Spanish authorities. Dabas, who wore a shirt, khaki-coloured trousers and a duffle coat, spoke only to give his name and date of birth at the 30-minute hearing. Mr Dabas was arrested 24 hours after his brother Mohannad Almallah Dabas, a Syrian national, was arrested in Madrid. The Spanish Interior Ministry has accused the two men of being linked to the recruitment of young Islamic radicals in Spain. It claims they used a flat in Madrid to house recruits, or people passing through. They are alleged to have been helped by a Syrian man, who has already been arrested and charged for his suspected role in the 11 March attacks. The bombings have been firmly attributed to Islamic extremists by Spain's public prosecutor. So far more than 70 people have been arrested, with 22 held on charges, over the bombings. A Moroccan cell with links to al-Qaeda claimed responsibility for the attack, and most of those arrested have been Moroccan citizens.
