Read this: On July 19, 2013, West was leaving LAX as he was surrounded by dozens of paparazzi. West became increasingly agitated as a photographer, Daniel Ramos, continued to ask him why people were not allowed to speak in his presence. West then says, "I told you don't talk to me, right? You trying to get me in trouble so I steal off on you and have to pay you like $250,000 and shit." Then he allegedly charged the man and grabbed him and his camera. The incident captured by TMZ, took place for a few seconds before a female voice can be heard telling West to stop. West then released the man, and his camera, and drove away from the scene. Medics were later called to the scene on behalf of the photographer who was grabbed. It was reported West could be charged with felony attempted robbery behind the matter. However, the charges were reduced to misdemeanor criminal battery and attempted grand theft. In March 2014, West was sentenced to serve two years' probation for the misdemeanor battery conviction and required to attend 24 anger management sessions, perform 250 hours of community service and pay restitution to Ramos.
