London police make 2nd arrest
Police arrest second man in connection to Thursday's attempted underground and bus attack; officials release photos, appeal for public's help; earlier, officers kill suspected subway bomber
A second man was arrested in London Saturday in connection to Thursday's attempted underground and bus bombings.
Scotland Yard said the man was arrested in Stockwell, the south London neighborhood where a second suspect was detained Friday and another man was fatally shot by police in a subway station.
The first suspect, who has not been named, was being questioned at a high-security London police station.
Police released photographs Friday of four men suspected of launching a second wave of terrorist attacks on London's transport system and said the attacks bore similarities to the fatal bombings on July 7.
Police said the bombs on Thursday partly detonated and contained homemade explosives.
Meanwhile, Metropolitan Police Commissioner Sir Ian Blair said the fatal shooting by officers of a man at a London subway station Friday was linked to the ongoing anti-terrorism operation.
The police photographs showed one man, wearing a dark shirt with "New York" across the front, running through a subway station. Another was shown on the top of a double-decker bus, while the other two men were shown at separate subway stations.
Blair, who is Britain's most senior police officer, told a news conference in central London that his force was facing its "greatest operational challenge ever" and that anti-terrorism officers were working around the clock.
Wires protrude from man's belt
Earlier Friday, plainclothes police chased a man through a south London subway station, wrestled him to the floor and shot him to death Friday as authorities attempted to track down four men suspected of setting off explosives around London.
Later, police said the man was directly linked to Thursday's blasts in the British capital.
Passengers described the suspect as a South Asian man who ran onto a train at the Stockwell station, and a witness said he saw wires protruding from the man's belt.
Police said the man was challenged and killed.
"I've seen these police officers shouting, 'Get down, get down!', and I've seen this guy who appears to have a bomb belt and wires coming out," one witness, Anthony Larkin, told the British Broadcasting Corp. "People were panicking and I heard shots being fired."
Another passenger on the train, Mark Whitby, said the man didn't appear to have been carrying anything, but said he was wearing a thick coat that looked padded.
"They pushed him onto the floor and unloaded five shots into him. He's dead," Whitby told the BBC " he looked like a cornered fox. He looked petrified."
Police would not say which armed unit was involved. Ordinary beat police officers do not usually carry guns, but armed police have become more common. Scotland Yard police headquarters said the policy of armed police was to "Shoot to stop" when there was an imminent threat to
life.
A police spokesman would not say whether officers had new instructions to aim for the head, if they suspected someone was a suicide bomber.
