Police arrested a 14-year-old Muslim boy at an Irving, Texas high school on Sept. 16 after the homemade clock he brought to school was mistaken for a bomb.
Ahmed Mohamed was taken to a detention center after showing the clock to his teachers.
Irving Police Chief Larry Boyd said Ahmed was handcuffed “for his safety and for the safety of the officers.”
The arrest set off a firestorm on social media, with the hashtag “#IStandWithAhmed” tweeted over 1 million times by that afternoon.
President Obama weighed in on Twitter, saying “Cool clock, Ahmed,” and sent him an invitation to visit the White House.
Ahmed said he plans to transfer from MacArthur High School.
