No charges for Ahmed Mohamed, boy, 14, arrested over clock A 14-year-old boy was arrested by police in Texas after a homemade clock he wanted to show his school teachers was mistaken for a bomb. Ahmed Mohamed told US media that he made a clock at home and brought it into MacArthur High School in Irving to show his engineering teacher. Another teacher saw it, and, concerned it looked like a bomb, alerted school authorities who called the police. His father fears the incident happened because of his son's Muslim background. BBC
