Ahmed Mohamed is a ninth-grader in Irving, Texas who likes to tinker with electronics. On Monday, according to the Dallas Morning News, he built a simple electronic clock — a project he said took about 20 minutes — and strapped it inside a pencil case.
He showed the project to his engineering teacher, who praised the design but advised him not to show it to other teachers. Later, in his English class, the clock beeped while it was in his bag. When he showed the project to his teacher, she thought it looked like a bomb.
According to the Dallas Morning News, the police arrested Ahmed and led him out of school in handcuffs. His school gave him a three-day suspension, and police are still investigating the incident.
