WOODSTOCK — A 17-year-old student was arrested at Woodstock High School on Friday morning in response to terroristic threats authorities say the teen sent out on social media Thursday night.

Lt. Jay Baker, spokesman with the Cherokee County Sheriff’s Office, said Lake Reynolds allegedly tweeted out on Twitter the message: “Planning on pulling a Columbine tomorrow guys, be prepared!”

“School officials were alerted to the posting after multiple calls from parents were made to the school who in turn notified the sheriff’s office,” Baker said.

The high school junior admitted to posting the message after he was removed from class, Baker said.

The tweet seemed to reference the Columbine High School massacre, the deadliest school shootout in U.S. history. In April 1999, two students at the Colorado high school gunned down 12 students and a teacher before each of the gunmen committed suicide. Twenty-three others were wounded during the shootings.

“He was not armed and there is no indication that Reynolds actually planned a ‘Columbine(-like)’ attack, however he is being charged with the threat,” Baker said. “Students should be aware that social media threats made about violence at a schools even when a hoax, will result in criminal charges in Cherokee County.”

Baker said Reynolds is being held at the Cherokee Adult Detention Center on an $11,200 bond.

In a letter home to parents Friday, Woodstock High School Principal Bill Sebring said school officials are working with the sheriff’s office and Cherokee County School District Police Department to investigate the matter.

“Although we did not find evidence of plans by anyone to actually conduct a terroristic event, we remain on alert,” Sebring wrote in the letter.
