CHILHOWEE, Mo. (NBC) -- Two weeks ago an angry mother called the Johnson County, Missouri Sheriff's office to report suspected child abuse.
According to the police report filed that day, the alleged abuse included her son being bound by duct tape at Chilhowee School.
The report states witnesses saw the school bus driver and the Chilhowee principal using duct tape to restrain a 5-year-old boy's hands.
The kindergartner has Asperger's syndrome and, according to his mother, was upset at that moment.
The mother of the boy, who filed the report, said another parent told her the school bus left the school once on September 25, and then returned after her son had an outburst.
That's when the duct tape was allegedly used for restraint.
"I don't know what I would have done," says Shawn Holt, father of another child at the school.
Holt said he was infuriated by the allegations.
"I think there ought to be criminal charges involved not only on the school bus driver, but also on the school because they covered this up for at least a week," he explained.
Superintendent Jeff Blackford refused an offer to comment on Wednesday and would not say if those involved in restraining the boy have been removed from duty or if he had communicated with parents since the alleged incident.
However, he did share a statement, part of which claimed "We hold all our staff members to very high standards and we expect our staff to appropriately supervise and manage students at all times."
Mother Linda Lujan sees the situation very differently than school district officials, and had a strong message for them.
"Get off your butts and teach your staff how to deal with kids with disabilities," Lujan said.
Her 7-year-old son Connor has Asperger's syndrome, too, and Lujan claimed he was threatened by the same bus driver.
"He told us that he started yelling and was kicking the seat and the bus driver stated that if he didn't shut his mouth, he was going to duct tape him," she recounted.
In the end, Lujan said Connor avoided duct tape restraint.
The allegations remain under investigation by sheriff's office and the school district.
Friends of the boy who was reportedly duct taped said the family is conducting its own investigation and is planning to pursue legal action.
