From Beeb tonight, and confirmed on Italian TV news: "Italy arrests 'UK bomb suspect' UK police have said that a man arrested in Rome is of "interest" to the investigation into the failed London bomb attacks on 21 July. Italian Interior Minister Giuseppe Pisanu had earlier said that Hussain Osman - a Somali-born British citizen - was one of the four suspected bombers. His brother was also arrested by police, said Italy's Ansa news agency. Details unclear Metropolitan police said they would be seeking Hussain Osman's return to the UK. Mr Pisanu said he was wanted in the UK over the Shepherd's Bush station attack. "The recent arrest, in Rome, of the Somali Hussain Osman, a naturalised British citizen and the fourth 21 July attacker, is truly worthy of praise," said Italy's interior minister in a statement. "The anti-terror operation, still ongoing, is part of wider international collaboration," Giuseppe Pisanu said. "It confirms, not only the strength of our security systems, but also the efficiency of international co-operation." The minister gave no details of the operation, said to have been carried out by anti-terrorist police units known as Digos. According to Italian media reports, Hussain Osman, 27, went to Rome to stay with a brother and was seized near the main train station, Termini. Based on unnamed police sources, Italian state broadcaster Rai said he had left London two days ago - travelling to Rome via Paris and Milan. He was traced through calls made from a mobile telephone to numbers in France and Italy, Rai said. Other accounts said he had been arrested in a flat in the Tor Pignattara area in the outskirts of Rome. Security was tightened significantly in Italy after the London bombings, but there was no indication from the authorities that the manhunt for the London suspects had shifted to Italian territory, says the BBC's Frances Kennedy in Rome.
