LONDON — British police arrested a fifth suspect Sunday in their frantic nationwide manhunt for the perpetrators of failed bomb attacks in central London and at the Glasgow international airport.
Authorities also carefully searched a suspicious vehicle outside the Scottish hospital where they had taken one of the Glasgow suspects, who suffered severe burns when he drove a Jeep Cherokee into the glass entrance to the main airport terminal Saturday. Security officers also temporarily shut down a portion of Heathrow Airport on Sunday to investigate reports of a suspicious package.
The new arrest came in Liverpool, where a 26-year-old man living in a low-income district was detained and taken to the high-security Paddington Green police station in London. Liverpool police said the arrest was made in connection with the two car bombs discovered Friday in central London.
TV reports said one key suspect remained at large but did not identify him.
New clues were surfacing almost hourly, and links between the London and Glasgow incidents were "becoming clearer," said counter-terrorism chief Peter Clarke, briefing reporters in the Scottish city.
Prime Minister Gordon Brown, himself a Scotsman, on Sunday urged British residents to continue to remain calm, even as the nation's terrorism alert rating remained at "critical," the highest level. In the first TV interview of his premiership he told the BBC One "Sunday AM" program that he recognized the present terrorism threat as "long term and sustained."
"[But] it's very important," he added, "that we the British people send a message to terrorists that they will not be allowed to undermine our British way of life."
On Sunday night, tens of thousands of people, undeterred by the threat of additional attacks, attended a London concert organized by Princes William and Harry as a tribute to their late mother, Princess Diana, on the day she would have turned 46. The concert, which featured performances by artists such as Duran Duran and Elton John, was guarded by armed police officers.
Armed officers, normally a rarity in Britain, patrolled public places across London on Sunday and are expected to remain on the streets indefinitely.
In his first public comments on the attempted bomb attacks in Britain, President Bush on Sunday praised the "very strong response" by Brown's government.
"It just goes to show the war against these extremists goes on," Bush said. "You never know where they may try to strike."
