A solemn-faced Nicolás Maduro was seen for the first time since his capture making a handcuffed perp walk inside New York City’s DEA headquarters — in which he oddly wished agents a “Happy New Year,” according to video and snaps. The toppled Venezuelan tyrant sported black sweats and a black hat as he clutched a water bottle while being escorted through the Chelsea facility before being taken to the Metropolitan Detention Center in Brooklyn Saturday night.
