In separate letters to the city of Irving, located west of Dallas, and the Irving Independent School District, lawyers said the ninth grader was wrongfully arrested, illegally detained and questioned without his parents.

The Mohamed family is asking for $10 million from the city and $5 million from the school district or they will file civil lawsuits within 60 days, the letter said.

“Understandably, Mr Mohamed was furious at the treatment of his son – and at the rancid, openly discriminatory intent that motivated it,” attorneys said in one of the letters.

The school district said in a statement its lawyers are reviewing the letter and will respond appropriately. City officials were not immediately available for comment.

The boy’s family said in October that they would be moving to Qatar and he had accepted an offer from the Qatar Foundation to study at its Young Innovators Program. The announcement came a few hours after he was at the White House for an astronomy night hosted by President Barack Obama.Ahmed won support from Obama and other major US figures, including Facebook Chief Executive Mark Zuckerberg, who said “having the skill and ambition to build something cool should lead to applause, not arrest.”

The family, now living in Doha, has also traveled the globe to meet foreign dignitaries.

Sudanese state radio reported that his father took him to meet Sudanese President Omar al-Bashir.

The Sudanese leader is accused by the International Criminal Court of masterminding genocide, crimes against humanity and war crimes during Sudan’s Darfur conflict.

Despite several television appearances and worldwide travel, the Mohamed family says the attention ruined their lives and eventually drove them out of the country, lawyers said.
