The Gahanna-Jefferson school district is adding to its security measures at Lincoln High School this week after a 16-year-old student allegedly posted a disturbing video on YouTube and made inappropriate tweets over the Labor Day weekend.

The Lincoln High School junior was arrested Sept. 3 and charged with inducing panic involving a school. He was being held at the Franklin County Juvenile Detention Center on Sept. 4.

The Columbus Bomb Squad conducted a sweep of the entire high school prior to the start of school Tuesday, Sept. 4, and will continue to do random sweeps throughout the week for precautionary reasons, Superintendent Francis Scruci said. Additional police personnel were scheduled to be on hand throughout the Sept. 4 to ensure the safety of students and staff.

The additional security measures are in response to a video uploaded via YouTube and Twitter at about 3 a.m. Saturday, Sept. 1. It was directed at Gahanna Lincoln High School students.

The content of the video was considered disturbing in nature and created fear and anxiety to students and parents of Gahanna schools, according to school officials.

The video was of a masked character from the movie, V for Vendetta, with a computer voice-over.

An additional video was posted on the morning of Sept. 3 in response to a local news report. That video claimed that no harm was intended to anyone but alluded that it was toward crashing the school computer network. The juvenile admitted to being angry about the way students were leading their lives.

In addition to the video, several Gahanna Lincoln students received inappropriate, rude and harassing tweets from a student using the Twitter account, @AnonymousRuler, at about 8 p.m. Friday, Aug. 31.

Many students informed high school principal Dwight Carter of the messages, so he consequently contacted Twitter to shut down the account. He also contacted the Cyberbullying Research Center for assistance.

As soon as the Gahanna Police Department received the information, Gahanna school resource officers, Gahanna-Jefferson Public Schools officials and the Gahanna police detectives bureau began to formulate a plan of action.

By early in the day Sunday, Sept. 2, detectives had developed an address and suspect. Subsequently, a search warrant was obtained and executed at about 10:35 a.m. Monday, Sept. 3. The juvenile was arrested, and computer and computer equipment were seized.

Scruci said the district worked closely with Gahanna police to protect the students and staff.

"We want to commend the many students who contacted Mr. Carter to make the district aware of the situation," he said. "Their approach to handling this situation in a positive and responsible manner is reflective of the majority of the Gahanna-Jefferson student body."
