An unnamed man flying from Nigeria to New York City found out he was added to a no-fly list somewhere above the Atlantic Ocean, when the plane stopped to refuel in San Juan, Puerto Rico. Officials won't say what he did or why he was added to the list after he had already boarded a flight. He was not immediately charged with a crime and Customs and Border Protection will only say that he is a "potential person of interest." From the article: "The man, a citizen of Gambia, was not on the no-fly list when he boarded the aircraft in Dakar, Senegal, said a US official who spoke on condition of anonymity because he was not authorized to discuss the issue publicly."
