Lawyers for a 14-year-old Muslim boy arrested after taking a home made clock to his Texas school say he was publicly mistreated and deserves US$15m.
A law firm representing Ahmed Mohamed sent letters demanding $10m from the city of Irving and $5m from the Irving Independent School District.
The letters also threaten lawsuits and seek written apologies.
Ahmed took his clock to school in September, and an educator thought it could be a bomb.
The teenager was arrested but never charged. He was suspended from school.
He went on to meet several political leaders, accepted an invitation to the White house, and was named as 'American Muslim of the Year' by The Council of American-Islamic Relations.
The family has since accepted a foundation’s offer to pay for Ahmed’s education in Qatar and has moved to the Persian Gulf country.
A spokeswoman said the city of Irving was reviewing the letter and had no comment.
