Man arrested after armed siege in central London

The suspect at the center of a three-hour siege that shut down part of a busy section of central London on Friday has been arrested, police said.

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.

Metropolitan Police said the 49-year-old man was in police custody and that searches of the building were ongoing. British media had claimed that the man was holding people captive, but police said they were "not aware of any hostages at this stage."

One eyewitness claimed earlier that the man had burst into the office of a training company, saying he was ready to blow himself up.
