The incident happened last November during a commute that lasted about 45 minutes.

In the video Billings posted on YouTube, the attack appears to go on for about 15 minutes.

“I lost my mind. I couldn’t believe what I saw. I couldn’t believe that there was an adult there that could have stopped it,” Audrey Billings told CBS News.

At one point during the assault, you can hear the child crying.

It also appears the bus driver never got involved.

“He heard cries of help and he chooses to do nothing and it could have been stopped within the first two minutes of the attack,” Billings said.

“The people, the adults there are responsible,” said Billings regarding what happened on the bus. “I can’t go help her.”

Dallas ISD said the driver was removed from that bus route.

Billings said she wants the driver taken off the streets — period.

DISD said it has taken steps to ensure the safety of students and provide additional monitoring.

The school district released the following statement on the matter:

“Dallas ISD has taken steps to improve our Transportation Services to further ensure the safety of students. The district has provided additional training and monitoring. We are dedicated to ensuring a safe environment for all students and remain committed to meeting the expectations of our parents and community.”

Billings said her daughter no longer rides the school bus.
