Watch | Muslim student arrested after homemade clock mistaken for bomb

A Muslim teenager detained by police after a teacher at his North Texas high school decided that a homemade clock he proudly brought to class looked like a bomb will not face criminal charges, a police chief said Wednesday. Ahmed Mohamed will not be charged with possessing a hoax bomb because there's no evidence the 14-year-old meant to cause alarm Monday at MacArthur High School in the Dallas suburb of Irving, according to police Chief Larry Boyd.
