FLORESVILLE, Texas -

A Texas Elementary School bus driver was caught on camera mocking a crying girl in the weeks leading up to spring break.

Video obtained by Local 6 sister station KSAT-TV from inside bus No. 67 shows the driver, known to students as "Ms. Pat," calling the young girl, "crybaby."

Then, a few seconds later, she invites the students to join in, chanting, "Ready? Cry, cry, cry!"

Even though the majority of the bus is chiming in, the little girl can still be heard crying in the background.

"'I want my mama,'" Ms. Pat hollers, taunting the sobbing child.

Monna Perez, whose children ride the same bus, was brought to tears watching the video.

"If you can't bully at school, why are they allowing it on the bus?" Perez said.

"She treated the child as if she was a child herself, bullying the child," said a mother who asked to be identified only as Lucy. "Having the other children follow her example, that's just wrong."

Lucy said her son had asked her that morning if she could pick him up instead of putting him on the bus. After seeing the video, she said she now knows why her son no longer wanted to ride the bus.

KSAT-TV sat down with Floresville Independent School District Superintendent Dr. Sherri Bays to show her the video and get her reaction.

"I was very concerned with that and it's definitely not appropriate," Bays said. "I think she's acting very childish and immature."

The driver no longer works for the school district, but no other details were released.
