Rob Kardashian, socialite Kim Kardashian\'s brother, was arrested after he tried joking around with a paparazzo in Miami. He was, however, released later. \"He was out with some friends when he saw a photographer taking pictures from across the street. We\'re told Rob thought it would be funny to start sprinting towards the photographer. But the photographer didn\'t laugh and instead ran away screaming for help,\" tmz.com quoted a source as saying. \"Rob followed the guy into a smoke shop to try and clear the air but the police saw the whole thing and decided to get involved,\" the source added. But after explaining to police that it was all a misunderstanding, Kardashian was released.
