After an investigation by local law enforcement, authorities say they have found no evidence that a bomb threat made at Forsyth Central High School is credible. 

According to an email sent to parents on Thursday morning, the threat was found written in a boys' bathroom stall at the high school and was shared by students on social media.

The letter states that the Forsyth County Sheriff's Office and Cumming Police Department "thoroughly investigated" the threat with sheriff's office bomb detection dogs.

"We found no evidence to support the credibility of the threat," the letter states. "We encourage you and your child(ren) to continue to 'see something, say something' to maintain a safe learning environment for all. If you have questions or concerns, please contact one of our school administrators."
