He said he took it to school on Monday to show an engineering teacher, who said it was nice but then told him he should not show the invention to other teachers. Later, Ahmed’s clock beeped during an English class, and after he revealed the device to the teacher, school officials notified the police, and Ahmed was interrogated by officers.
Why was the device in English class in the first place, especially after the engineering teacher told him not to show it around? When confronted by police and his English teacher, why didn’t Mohammed just tell them to talk to the engineering teacher? When police asked Ahmed what the device was and why he brought it to school, according to WFAA:
Officers said Ahmed was being “passive aggressive” in his answers to their questions, and didn’t have a “reasonable answer” as to what he was doing with the case. Investigators said the student told them that it was just a clock that he was messing around with. “We attempted to question the juvenile about what it was and he would simply only say it was a clock. He didn’t offer any explanation as to what it was for, why he created this device, why he brought it to school,” said James McLellan, Irving Police.
