A social media threat directed at "MHS" that went viral originated in Virginia, according to the Fulton County Sheriff's Office.
The suspect — a juvenile male — is in custody, sheriff's officials said in a Facebook post late Sunday:
A Snapchat post showed an arsenal of guns with a message warning students to not "go to school tomorrow at @MHS."
A screenshot of the post was widely circulated in areas where there are schools with the "MHS" initials. In the Capital Region, that includes Mayfield and Mohonasen high schools.
But the post was referring to Monticello High School in Charlottesville, Virginia, according to Fulton County sheriff's officials.
Deputies were stationed Monday outside Mayfield High School:
Deputies in Fulton county were outside Mayfield HS this morning after this Snapchat screenshot went viral on social media, threatening students not to go to school. But this image actually originated from a school district in Virginia that also has “MHS” in its name. pic.twitter.com/QPj7pbpfhz— Steve Maugeri (@CBS6SteveM) January 8, 2018
A Facebook post from Mohonasen schools also sought to reassure after "some concern in the community":
The social media post was determined "to be a hoax and not a valid threat," according to NBC29 in Charlottesville.
