Cops say they were protecting the boy and others after his emotional outburst.
His mother says it was just plain wrong.
"Can't go to sleep or eat," Joseph Anderson said.
7-year-old Joseph Anderson says he can't sleep or eat after he was handcuffed at school.
His mother says what police did was out of line.
"I feel like my son was being discriminated against and retaliated against because of his disability," said Jessica Anderson, Joseph's mother.
The first grader was painting an Easter egg when he became upset.
He was handcuffed and taken to the hospital.
New Schools Chancellor Dennis Walcott says he looking into the incident.
But some of his comments haven't exactly reassured Jessica Anderson and her attorneys.
About using handcuffs, Walcott has reportedly said, "There are occasions when it may need to be done, and I think it's the responsibility of the principal and school safety to work together to make that determination."
Jessica Anderson is planning a lawsuit and she says she wants the principal of the school and everyone else involved to be disciplined.
"I want for the principal to give up her seat, because she doesn't know what she's doing," Anderson said.
