Ahmed Mohamed, who was arrested in Texas for taking a homemade clock to class, is seeking $15 million from the City of Irving and MacArthur highschool.

The teenager was held by police and suspended from his school because his teacher mistook the clock for a bomb.

Ahmed Mohamed’s lawyer said in a letter that the incident, which made global headlines, sparked threats against the boy and left him deeply traumatized.

The 14-year-old and his family have since moved to Qatar to complete his education.

The arrest sparked outrage, sympathy and the trending hashtag #StandWithAhmed.

Ahmed Mohamed’s lawyers are asking for $10 million from the city of Irving and $5 million from the Irving Independent School District, saying that Ahmed Mohamed was “publicly mistreated” and remains scarred.

In addition to the compensation they want an apology, saying that in the aftermath of the arrest, he received threatening emails and feared for his safety, causing “severe psychological trauma”.

The lawyers will file a civil action suit if the school does not comply within 60 days, they said.

“Irving Police officials immediately determined that the clock was harmless. The only reason for the overreaction was that the responsible adults involved irrationally assumed that Ahmed was dangerous because of his race, national origin and religion,” the lawyers wrote in a letter to the City of Irving.

Ahmed Mohamed told reporters at the time it was “very sad” that his teacher thought his clock was a threat.

His arrest was sharply criticized, and he received an outpouring of support including an invitation to the White House.

In October, Ahmed Mohamed met Sudanese President Omar al-Bashir in the Sudanese capital, Khartoum. The boy’s father is a Sudanese immigrant to the US who once stood as a presidential candidate against Omar al-Bashir.

Ahmed Mohamed also met Google co-founder Sergey Brin and officials from Turkey, Sudan and Jordan.

Texas officials defended their decision, saying they were only concerned with the safety of students.

The Qatar Foundation for Education, Science and Community offered him a full scholarship in October.

Ahmed Mohamed’s family announced they would be leaving Texas and moving so he could attend school there.
