A special needs teacher and two aides were arrested after a mom secretly recorded them allegedly threatening to hurt children.

Former educator Christina Lester along with June Yurish and Kristin Douty have been charged with failing to report abuse or neglect.

The shocking audio recording was obtained by Amber Pack, whose daughter attended the Berkeley Heights Elementary in Martinsburg, Virginia.

She secretly planted a small device in her eight-year-old's hair barrette after the girl told her she didn't want to return to class, ABC7 reported,

After listening back to the clips, the comments left Pack 'unable to eat for three days' and 'so upset' that every time she looked at her daughter she would 'start crying'.

Former special needs classroom aides Kristin Douty (left) and June Yurish (right) have also been charged. It's alleged that they and teacher Lester threatened to abuse kids at the school

In one section a female voice is heard saying: 'This one I could punch her right in her face.'

'I ought to backhand you right in your teeth. How is that for anxiety?' another said.

'I'm going to pull your hair until you start crying,' one adult commented.

Those were just some of the threats that featured in addition to comparing the kids to a 'wench' and a 'pygmy.'

In the majority of the clips, the children can be heard crying in the background.

Pack, whose daughter has nonverbal autism, alerted the school district and Martinsburg Police Department to the recordings in October.

They concluded there was no criminal wrongdoing and it's claimed the school tried to suppress the incident.

Another parent whose six-year-old son Owen attends the school claims they were not informed about the recording.

Kasey Murphy was alleged to have only found out about the clip after it was posted on Facebook.

She told ABC: 'I've never heard from the principal. Never heard from the Superintendent. I've never heard from any of them.'

Since then Attorney General Patrick Morrissey has used his executive privileges to seek an injunction, which led to criminal charges being filed against the former-staff and a further civil case.

Morrissey said: 'These arrests send a strong message — that child abuse will not be tolerated and must be reported.

'We must continue working to ensure vulnerable children are protected, especially at school.'

The civil complaint was filed against the three arrested in addition to others in the education sector.

The other listed defendants are school principal Amber Boeckmann, Berkeley County deputy superintendent Margaret F. Kursey and the Berkeley County Board of Education.

He claims Boeckmann and Kursey actively tried to 'obscure evidence with a flawed investigation.'

Kursey is also alleged to have given an order to 'destroy a recording of the verbal abuse and failed to report the matter to Child Protective Services.'

He included the board due to Lester, Yurish and Douty being employed by them at the time of the alleged incidents.

Lester, Doughty and Yurish were booked into Eastern Regional Jail on August 16.
