The New York Post, Fox News and NBC News all reported that someone was being held in connection with the explosions. The Post went the furthest, saying that the man was a Saudi national and was 20 years old. These reports were denied by the Boston police commissioner, who told both reporters and a full press conference that there was nobody in custody. http://www.huffingtonpost.com/2013/04/15/boston-attack-media-conflicting-reports_n_3087916.html
