Parents outraged after school police allegedly handcuffed and tased a 7-year-old special needs child

A 7-year-old special needs student in Dallas was handcuffed, tased, and left with bruises after an emotional outburst in class last week.

Yosio Lopez, who is diagnosed with attention deficit/hyperactivity disorder along with another mood disorder, began banging his head against a wall in class, according to investigator David Ramirez, who was hired by the family. Yosio's school aide was not present to defuse the situation, so administrators at Gabe P. Allen Elementary School called school district police to handle the situation, Ramirez told CNN.

Yosio told his mother, April Odin, that a Dallas ISD officer called to the scene forced him onto a desk with his hands placed in handcuffs behind his back while the school principal placed her elbow on his neck, choking Yosio in an attempt to restrain him during the incident. He also said he was tased.

"The boy did vividly describe being shocked and his body convulsing. … And he was very clear about that," said the family's attorney, Amar Dhillon.

After the outburst at school, DISD police transported Yosio in handcuffs to a local mental health facility without his mother's consent, where the 7-year-old boy was committed for almost a week. He was heavily sedated during his stay, and the behavioral hospital would not allow his mother to see him during the first two days because they insisted he could pose a danger to himself and others.

Yosio was released from the hospital Monday and is now home with his mother.

DISD released a statement, explaining that it could not comment on the matter due to confidentiality laws.

"The Dallas Independent School District is committed to educating the whole child each day, and in doing so, we believe in providing a productive learning environment that is safe for all staff and students. While there has been media interest into an alleged incident at one of our Dallas ISD campuses, due to federal confidentiality laws protecting the privacy of all students and their families, we are unable to publicly confirm or deny the matter reported."

A district spokeswoman told The Associated Press that district police were responsible for the actions taken during the incident.
