Six middle school honors students from Nevada were arrested for allegedly creating or contributing to an “Attack a Teacher” Facebook event scheduled to take place Friday morning at two separate Carson City middle schools.

The six girls -- one age 13, the others 12 -- all are charged with conveying a threat for allegedly posting comments on the “Attack a Teacher” Facebook page. One of the girls was also responsible for creating the online event, Carson City Sheriff Ken Furlong told FoxNews.com. They have since been released to their parents.

About 100 people were invited to the “Attack a Teacher Day” event, Furlong said. Jessica Rivera, the school district’s resource officer, said it was scheduled to take place Friday morning between 7 a.m. and 9 a.m. at both of the school district’s middle schools.

Fourteen students accepted the invitation, but the six girls in particular were responsible for the posts that appeared to threaten specific teachers, Rivera said.

“There was a wide range of different ages and male and female, but it was all girls that posted on the wall,” Rivera said.

She said there was no specific mention of weapons or details about how they planned to attack a teacher, but teachers at both schools were named.

“The posts included things like 'I’m attacking [teachers name]' or 'Down with [teacher’s name],' and one of them said 'Die [teacher’s name],'" Rivera said.

School officials were alerted to the page by a parent, and on Wednesday morning, the girls were called into a meeting with school officials, who said the girls admitted to their involvement with the Facebook event.

The six young girls are all honors students with no history of troublemaking, Rivera said, adding that all appeared extremely remorseful.

At the end of the meeting, the police were brought in and the girls were arrested on charges of conveying a threat and will appear before the juvenile magistrate at an undetermined later date.

Furlong said one of the offenders told police officers “Attack a Teacher Day” was supposed to be a joke.

“She thought it was going to be funny. Clearly that’s not the way that we view threats,” Furlong said. “They just clearly don’t understand the lethal potential of something like this going out of control. And that’s to assume the kids were sincere in that they thought it was funny. But the actual threats posted were not funny at all.”

They could have been deadly, he said.

Rivera said the girls likely would be hit with a small fine or receive community service, depending on what the district attorney’s office decides to pursue.

Superintendent Richard Stokes told FoxNews.com five of the students attended Carson Middle School and one goes to Eagle Valley Middle School.

He said five of the students were suspended for three days, and the other was suspended for five days, noting that the longer suspension was due to a prior disciplinary issue.

“The principal identified these kids as good kids,” Stokes said. “The majority of the students involved were not frequent visitors to the principal’s office.”

The event the girls are alleged to have promoted also apparently violated Facebook's policies, spokesman Andrew Noyes said.

"We're sensitive to content that includes pornography, bullying, hate speech, and actionable threats of violence and we react quickly to remove content that violates our policies when it is reported to us," he said. "Facebook is highly self-regulating and leverages its more than 500 million users to keep an eye out for offensive content. We encourage users to report such content and we have a large team of professional reviewers who evaluate these reports and take action per our policies.”
