The Texas teenager who was arrested after bringing a homemade clock to school has sent letters to the city of Irving, Texas, as well as the Irving school district, demanding $15 million and a written apology. If he doesn't get both within 60 days, Ahmed Mohamed's lawyer says he'll file a lawsuit.

Mohamed's saga began in September, when one of the boy's teachers suspected that the homemade clock he brought to school may have been a bomb. The school called in police, who handcuffed Mohamed and questioned him. The image of the stunned, handcuffed 14-year-old in a NASA T-shirt went viral. The boy's father said his son was victimized because he was a Muslim.

News reports on Mohamed's plight vaulted him to international celebrity status. He accepted an invitation from President Obama to visit the White House and saw an outpouring of support from politicians and technology leaders, including Twitter shout-outs from Google, Mark Zuckerberg, Google co-founder Sergey Brin, Hillary Clinton, and MIT.

The letters, published by Dallas TV station WFAA , describe in detail the events of September, from the supplies Mohamed used to build his clock to the teachers he showed it to.

Mohamed's lawyer says his Fourth Amendment rights were violated and that police tried to coerce a confession to a "hoax bomb" violation. Officials later "castigated" Mohamed in public, he claims, including with an appearance by Irving Mayor Beth Van Duyne on the Glenn Beck show. The letter continues:

"From the time Ahmed was escorted out of class and into the interrogation room, he was treated by ALL of the adults responsible for his safety as though he had no rights at all," the letter states. "This was a complete breakdown in the City's protection of Ahmed's fundamental constitutional rights... This whole chain of events was an extraordinary rendition in miniature, in which Ahmed was treated as though he had no rights at all, despite his American citizenship."

The letters say Ahmed has suffered "clearly severe" damages in the aftermath, including his treatment on the Glenn Beck show, online harassment, and having his name and likeness "forever associated with arguably the most contentious and divisive socio-political issue of our time... Ahmed's reputation in the global community is permanently scarred."

The letter to Irving Independent School District demands $5 million in damages, while the letter to the city of Irving demands $10 million. Both demand a written apology as well.

"The numbers are huge, and we admit that," Mohamed family attorney Kelly Hollingsworth told WFAA. "But the damages caused against this young man and his family are incalculable."

The Mohamed family is currently living in Doha, Qatar, where they accepted an invitation last month for Ahmed Mohamed to study at the Qatar Foundation. However, the letters sent this week to Irving ISD says the family is living in Doha "for personal security reasons" and desires to return to Texas.
