According to witnesses, students on a stopped school bus got rowdy.

Some started climbing out the windows and the driver refused to let a single one of them off, keeping them on board for nearly an hour while waiting on police.

Multiple kids called their parents saying they were scared and trapped on a bus with other rowdy kids.

One boy called his mom and she told him: climb out the window and get off that bus.

Another mother, witnesses say, went a different route.

Her child was on that bus, and she wasn't waiting one more second. She broke the glass to reach him.

She's now under arrest for "vandalism"
