Pittsburgh, PA – Pittsburgh elementary school teacher Janice Watkins (pictured) was brutally beaten by a parent on Wednesday.

The attack was revenge for Watkins disciplining the child of the assailant.

That suspect has been arrested and identified as Daishonta Marie Williams, 29.

The incident started Wednesday afternoon at Pittsburgh King PreK-8 School on the North Side, according to CBS News.

Janice Watkins, 46, confiscated a cellphone from a fourth-grade female because the district has a strict no-cellphone policy. That fourth-grader responded by badly biting Watkins.

Shortly thereafter, the students parents came to the school and Williams told Watkins that she was “going to get even.”

Watkins then left to get the bite wound checked out at a local clinic, and she was followed by Williams and at least one unidentified male.

As Watkins stopped at a red light at Route 65 and the West End Bridge, Williams’ black SUV pulled up.

“She said, ‘I put my window down, and the woman threw a brick through my window,’ and hit her in her face,” Watkins’ mother told CBS News. “And that’s when she said, so-and-so ‘I told you that I would get you,’ and [Watkins] said, ‘When I got out of that car,’ she said, ‘I didn’t realize it was two other people,’ she said, but she felt something hit her in the back, and it was two men.”

After the beating, the suspects took off and Watkins called 911.

“Her head is hurting real bad, her face is right on the one side it’s swollen,” Watkins’ mother continued. “So they took her down. They said they want to do a scan to make sure everything’s OK.”

Williams has since been arrested and is being charged with aggravated assault, stalking, terroristic threats, and recklessly endangering another person.

The suspects with Williams have still not been identified or located.
