A Denver area second-grade teacher is accused of taping her students' mouths shut when they wouldn't be quiet.

The incident happened Thursday at Fulton Academy, a charter school in the suburb of Aurora. Police are investigating and the unidentified teacher is on paid administrative leave.

According to KUSA-TV, one parent said all 28 kids in the class may have been affected.

"My daughter's been in the house crying, begging me not to send her back to school. (She) said that she'll do good in home school and she promises. She doesn't want to go back to a public school," Tenisha Bynes said.

The girl said the punishment was painful.

"When she put it on, it was like, OK, and then, like, it started to hurt my mouth right here. It's also hard for me to breathe with the tape, too," she said. The girl's name is being withheld because of her age.

The teacher did not return a phone call seeking comment.

Aurora Public Schools issued a statement saying it's taking this seriously and will conduct its own investigation
