This video image taken from amateur video shows heavily armed, masked police entering a building in central London Friday April 27, 2012 after a woman reported that a mentally unstable man had walked into her office threatening to blow himself up. Scotland Yard said in a statement that police were called to Tottenham Court Road, a busy central London avenue, just before noon and had sent a negotiator to the site. Office supplies, including computer monitors, were being thrown from the building's fifth floor window. (AP Photo/Amateur video via AP video) less
