(CNN) - The windmilling fists and stomping feet rain down blows on the 13-year-old boy.
Trapped on the floor between the bus seats, he cries out as he receives fierce punch after vicious kick from the three bigger, older youths.
As the relentless assault unfolds, the driver of the Florida school bus alerts the dispatcher, pleading for aid.
But he doesn't physically step in to help.
The bus driver, at least according to his school's policy, did nothing wrong.
'Get somebody here quick'
The attack took place July 9 in Pinellas County, Florida. But the horrific cell phone video - and the surveillance video - came out only recently.
As the boy is pummeled, the bus driver John Moody yells at the assailants to leave the boy alone.
He also asks dispatchers to send help.
"You gotta get somebody here quick, quick, quick, quick," he says. "They're about to beat this boy to death over here."
"Please get somebody here quick. There's still doing it," he adds. "There's nothing I can do."
Moody, 64, says he was too afraid to step in.
"The three boys just jumped on him and started pounding on him. And I did all can," he told CNN affiliate WFLA. "I was looking. It was like I was in shock. I was petrified."
Not required to intervene
The ferocity of the attack left the 13-year-old with two black eyes and a broken arm.
"There was clearly an opportunity for him to intervene and or check on the welfare of the children or the child in this case and he didn't make any effort to do so," Chief Robert Vincent of Gulfport Police Department told the affiliate.
According to Pinellas County school policy, the bus driver isn't required to intervene, only to call dispatch.
He can step in, if he feels it's safe.
Other counties actually forbid drivers from physically stopping fights.

(CNN) - Haralson County, Georgia, school bus driver Johnny Cook couldn't get the story out of his head: A middle school student told him he hadn't eaten, and had been turned away from the lunch line because he owed 40 cents. Cook wrote about it on Facebook, and the story spread.
Haralson County Superintendent Brett Stanton says it didn't happen that way; the child would have been offered a bagged lunch, Stanton told CNN affiliate WGCL, but he didn't go through the lunch line.
Cook says he still believes the student; the bus driver was fired after he refused to remove the Facebook post and apologize. "I'm proud that I was able to take a stand where others might not have been able to, and that I can maybe, in some little way, cause a change," Cook told WGCL.
It's not the first time a student has reported going without a meal because of school lunch debt; in some cases, they've been told to dump the food they've selected and are given an alternative snack, such as cheese and juice. Middle school students in Attleboro, Massachusetts, were turned away from lunch earlier this year, and about 40 elementary students in Edgewood, Kentucky, went without regular lunch during state testing period because of overdrawn accounts, CNN affiliate WCPO reported.
