Paul and Christina say their 14-year-old daughter was attacked Saturday at halftime of a basketball game at Burlington High School.
A student recorded video of the attack on a cell phone, and the video continues to circulate, though the parents are unable to find it, they say.
9NEWS is not identifying the student or the parents' last names to protect their online identity.
Burlington's Police Chief Barry Romans and Superintendent of Schools Tom Satterly both confirmed a student took cell phone video of the attack.
Satterly said an administrator immediately told the student to delete it from her phone, but was unaware if the student actually sent it to others.
The police department is also actively looking for the footage.
"If we find the video, we will put an end to it," Burlington Police Chief Barry Romans said.
Satterly said he took appropriate action against the multiple students involved.
"We followed our policies and procedures," Satterly said. Satterly said the school district is also looking for any online footage students are still accessing.
"Our daughter is taking it harder about the video because people are bringing it up every single day," Christina said.
They want to make sure other parents know to immediately try and stop videos like this from getting out before they spread too far.
"They said 'If you open it up on Youtube, it's one of the first videos.' And that's what all of them keep saying. It can't be. We cannot find this video," said Paul, the victim's father.
"It bothers me that everybody thinks we're making a big deal about it," Christina said. "But it's my daughter."
In Colorado, schools and students have a resource to deal with cyber bullying.
Safe2Tell was created after the Columbine Commission Report's recommendation that students would be more likely to report threatening behaviors if they had a safe, anonymous way to do it.
Since 2004, an organization called Safe2Tell says it has received more than 5,000 tips. More than 1,200 have been bullying reports.
"The kids in that school are going to know. And we would ask them to report that to Safe2Tell," Safe2Tell Executive Director Susan Payne said.
Payne also said schools should have a code of conduct that deals with on-campus and off-campus activity.
"The student videotaped an assault. That is evidence. And it's critical," she said.
