A high school student who had sex with his teacher has filed a federal lawsuit against the school system and the former teacher. The boy's parents joined him in the lawsuit.

The lawsuit, filed Monday in federal court, claims the Jones County school system was negligent for allowing the sexual relationship to happen.

The lawsuit says the 17-year-old boy suffered severe physical, mental and emotional trauma after being "sexually exploited, assaulted and abused" by Shebana Rajput.

The suit says the science teacher made sexually provocative contact with the student on school property, both during and after school hours. It says the sex began in March 2008, with Rajput providing alcohol, gifts, money and a cell phone to the 17-year old.

It claims the teacher purchased the student a car and even promised to marry him. The lawsuit says the boy was ridiculed by a former coach, who blamed him for the teacher's arrest.

Rajput pleaded no contest to one count of sexual activity with a student and was sentenced Tuesday to 45 days in jail, plus 3 years of probation.
