A 12-year-old has been charged with disturbing schools for posting a Snapchat threat that led Mount Pleasant Police and the Charleston County School District to place several Mount Pleasant schools on lockdown Tuesday morning.
Police say they called for an administrative "Code Yellow" lockdown after a school resource officer was notified by staff at Laing Middle School that several students had received a threatening Snapchat message.
"Code Yellow" lockdown means school operations continue as normal with restrictions placed on entry and exit of school buildings, according to Charleston County School District spokesman Andy Pruitt.
The lockdowns started around 8:20 a.m., and were lifted shortly after 10:20 a.m. police say.
Laing Middle School officials later confirmed the person who made the threat was not a student at the school.
Schools included in the lockdown were Thomas Cario Middle, Laurel Hill Primary, Pinckney Elementary, Laing Middle , Moultrie Middle, Carolina Park Elementary, Jennie Moore Elementary and Wando High.
