LONDON (AP) -- Police snipers and heavily armed officers put several blocks of central London's shopping district into lockdown Friday after a man allegedly armed with gas canisters entered an office building and threatened to blow himself up.
Police said a 48-year-old man was arrested hours after a stand off with police at Advantage, a training company near London's Tottenham Court Road that offers tests for truck drivers.
A shirtless man in green khaki pants was seen being led out with his hands behind his back by two unarmed officers. Armed officers followed behind.
British media had claimed that the man was holding people captive, but police said they were "not aware of any hostages at this stage." Police and security personnel said the incident was not terror-related and presented no risk to the upcoming 2012 summer Olympics.
