MYRTLE BEACH, SC (WBTW) – Myrtle Beach Middle School was on lockdown Wednesday afternoon after a “threat” was discovered inside the school, police confirm.

Myrtle Beach Police responded to the school just before noon Wednesday and was on scene until about 1 p.m.

Captain Joey Crosby with the police department explained in a video posted to Facebook that a threat was discovered on an interior wall of the school, although he did not give details about the threat. School staff initiated a lockdown immediately after discovering the threat to keep the students safe.

Horry County Schools Spokesperson Lisa Bourcier says a “threatening message written on a wall” prompted school staff to call police and ask for help in determining who may have written the message.

“At this time all students are safe and are not in danger,” Capt. Crosby says in the video.

Bourcier asked that parents not come to the school during the lockdown, which has been lifted around 1:15 p.m.  

The Myrtle Beach Police Department plans to keep parents and the community up to date through posts to Facebook and Twitter.
