A Muslim schoolboy arrested in Texas after a teacher mistook his homemade clock for a bomb won invitations to visit the White House, Google and Facebook on Wednesday amid a surge of public support.
President Barack Obama congratulated Ahmed Mohamed, 14, on his skills in a pointed rebuke to school and police officials who defended his arrest amid accusations of Islamophobia.
"Cool clock, Ahmed. Want to bring it to the White House? We should inspire more kids like you to like science. It's what makes America great," Obama tweeted.
A photo of Mohamed standing in handcuffs while wearing a t-shirt with the US space agency NASA's logo was retweeted thousands of times in a matter of hours and "#IStandWithAhmed" became the top trending hashtag on Twitter.
The son of Sudanese immigrants from from Irving outside Dallas, Mohamed told the Dallas Morning News he hoped to impress teachers by bringing the clock to school on Monday.
- 'They took it wrong' -
"My hobby is to invent stuff," the teen said in a video posted on the paper's website, filmed in his electronics-filled bedroom.
"I made a clock. It was really easy. I wanted to show something small at first... they took it wrong so I was arrested for a hoax bomb."
Mohamed loved robotics club in middle school and was hoping to find something similar at MacArthur High school, but did not get the reaction he hoped for when he showed the clock to his engineering teacher.
"He was like, 'That's really nice,'" Mohamed said. "'I would advise you not to show any other teachers.'"
When the clock's alarm went off in another class, his teacher told him it looked like a bomb and confiscated it. The school called the police and Mohamed was taken away in cuffs amid suspicion he intended to frighten people with the device.
- 'Suspicious device' -
Police said Wednesday they have determined that Mohamed had no malicious intent and it was "just a naive set of circumstances."
Irving police chief Larry Bond insisted that Mohamed's ethnicity had nothing to do with the response.
"Our reaction would have been the same either way. That's a very suspicious device," Bond told reporters.
"We live in an age where you can't take things like that to school."
He insisted officers did the right thing when they handcuffed Mohamed and brought him to a juvenile detention center for questioning. All prisoners are handcuffed for their own safety, Bond said, adding "unfortunately we've had people jump out of cars."
A school district spokeswoman also stood by the establishment's response, telling reporters that any one who saw the homemade clock would understand that "we were doing everything with an abundance of caution."
A photo provided by police to local media showed a flat, rectangular red digital clock face screwed into the dark plush interior of a silver case along with a circuit board and some wires.
- 'Bring your clock' -
White House spokesman Josh Earnest called the incident an opportunity to "search our own conscious for biases that might be there."
"At least some of Ahmed's teachers failed him," he said, adding that "this has the potential to be a teachable moment."
The Council on American-Islamic Relations said the heavy-handed response was suspicious given the political climate in Irving, where mayor Beth Van Duyne has claimed that Muslims are plotting to impose Sharia law in America.
"This all raises a red flag for us," said Alia Salem, who directs the council's North Texas chapter.
Wired magazine was among those who responded to the incident with a mixture of humor and horror, posting an article entitled "How to Make Your Own Homemade Clock That Isn't a Bomb".
Facebook founder Mark Zuckerberg told Mohamed to "keep building," saying: "I'd love to meet you."
Zuckerberg may have to wait. Along with the invitation to astronomy night at the White House next month, Mohamed also got invitations to drive NASA's Opportunity rover and visit Google.
"Hey Ahmed- we're saving a seat for you at this weekend's Google Science Fair...want to come? Bring your clock!" the online giant tweeted.
Mohamed's family launched a Twitter account Wednesday to thank his supporters using @IStandWithAhmed as his handle.
"Thank you fellow supporters. We can band together to stop this racial inequality and prevent this from happening again," read a tweet that included a photo of the smiling boy in his NASA t-shirt holding two fingers up in the sign of victory.
The hashtag #IStandWithAhmed had been tweeted over 370,000 times by early afternoon Wednesday, Twitter said.
