The 12-year-old boy, who is autistic, had several bruises on his face.
"I think she was evil and mean spirited about it," said Joan Ortiz, the victim's mother.
Joan Ortiz describes her son as sweet and loving and says that he is also autistic.
Ortiz says she could not believe her eyes when she says the woman who was supposed to take care of him on the bus, in her words, attacked him.
"He takes his foot and goes around getting on and she grabs him around the neck and pulls him over and with the mirror hits him in the face," Ortiz said.
She says her very first impulse was to get to him.
"I said to her, "Did you hit my son?" And she said, "I'm not going to let your (expletive) son hit me'," Ortiz said.
Ortiz says after the alleged assault police were called and the matron, 40-year-old Gina Rosado, was arrested.
"It just seemed as if it had happened before, that's what upset me," Ortiz said.
Each day, Matthew and nine other kids get a ride on the school bus 45 minutes north of where they live in the Bronx to Purdy, New York, to the Westchester School for Exceptional Children.
The bus company is contracted by the school and the school is paid for by the New York City Department of Education because Matthew has special needs.
The Dept. of Education spokesperson confirms they are investigating and that the matron has been suspended.
"I just want to make sure she never works near children again," Ortiz said.
