"There was a student at the school being harassed by other students," said Chief Deputy Bob Hetske of the Wayne County Sheriff's Office.
A 16-year-old Sodus High School student is accused of threatening a 14-year-old classmate.
"The victim in this case received numerous tweets."
Tweets, which police say included the line "If karma doesn't hit you I gladly will."
"A threat is a threat, and no person should be influenced of altering their daily activities or things they have to do because of a threat."
The incident led to the arrest of a 16-year-old girl. We're not reporting her name, but school officials and Wayne County authorities say it's a clear case of a growing problem: bullying through social media.
"We all know once you say something, you cannot take it back. Even if you say you're sorry a million times, it's out there."
The Sodus Central School superintendent refused to speak with us on camera but did release a statement. It reads that the district:
"...has a policy against cyber bullying and the district enforces this policy. We take our duty to prevent cyber bulling very seriously."
It was a school resource officer who brought the alleged cyber bullying to the attention of administrators.
Authorities say the dispute stemmed from the resignation of a coach and teacher at the school, and an accusation that the alleged victim may have played a role.
"Which subsequently was not true," Hetske said.
The 16-year-old is charged with aggravated harassment and endangering the welfare of a child.
Hetske says for parents, for their kids – for anyone – there is a lesson here.
"With every kid having a cell phone on them, the spontaneous of their thoughts being transferred, hit a button and it's gone."
