IRVINE (CBS/AP) — An autistic teenager who was dragged from class and handcuffed has sued the Irvine Unified School District.

KNX 1070’s Ron Kilgore reports the federal suit claims excessive force was used on former Irvine High School student Adam Stone.

In April, a teacher ordered the 18-year-old Stone to leave class for talking too loudly.

The lawsuit filed at U.S. District Court in Santa Ana, claims that a campus guard and two other men dragged the boy out and forced him to the ground. He was detained by Irvine police, handcuffed and put in a patrol car where he kicked out the window.

Stone was then hit by flying glass after the window shattered, according to the lawsuit.

The suit says the boy’s emotional state escalated because the guard and police weren’t told he was autistic and didn’t follow a previous plan to deal with his behavior.

District spokesman Ian Hanigan declined to comment on the suit.
