Ahmed Mohamed, a 14-year-old student at MacArthur High School in Irving, Texas, knew his homemade invention was just a clock -- but when he pulled out the device to show his English teacher what he had made, things took a very different turn.

"She was like, 'it looks like a bomb,'" the ninth-grader told the Dallas Morning News. "I told her, 'it doesn't look like a bomb to me.'"

On Monday, Mohamed was arrested and taken to a juvenile detention center under suspicion that the clock was actually a hoax bomb, the paper reported. On Wednesday, police said they will not charge Mohamed because there's no evidence that he meant to cause any harm.

In a video provided by the Dallas Morning News, he said he was "interrogated" by the local police and had his fingerprints taken before being released to his parents later that day.

"The clock was in a box you could get from Target for like $5 or $10, and they were telling me it was a suitcase, briefcase," Mohamed said in the video. "A movie bomb, which is what they were charging me of." According to the Dallas Morning News, the clock was made from a circuit board wired to a digital display.

Mohamed has been suspended from school for three days, and police are "still investigating the case," the Dallas Morning News reported Tuesday.

Mohamed's father expressed outrage, referencing post-9/11 stigmas against Muslims as a motivator behind the incident. The local chapter of the Council of American-Islamic relations also expressed concerns, the Dallas Morning News said.

In the video, Mohamed said that inventing things is his hobby.

"I never said anything about 'I have a bomb,'" Mohamed said in the video. "It made me feel like I wasn't human. It made me feel like a criminal."
