An individual is in custody and is being questioned by police following a lockdown in the Polk School District this afternoon, according to Cedartown Police Chief Jamie Newsome.

Newsome said the investigation continues into a threat of violence against Cedartown and Rockmart high schools which caused the entire district to go into lockdown around 12:45 p.m.

He did not provide any other identifying information other than to say the person of interest is male. No charges have yet been filed. 

Dismissal for Polk School District students began around 4:15 p.m. after police gave school administrators an all clear. Students were held after normal dismissal times as police investigated a potential threat of violence, according to Superintendent Laurie Atkins. 

"We've been asked by our local law enforcement agencies to continue to maintain the security measures we currently have in place until the investigation can be completed," Atkins said in an email. "We will release all students shortly...we will release car riders and buses will resume regular routes as soon as we are allowed to do so."

Atkins earlier sent out the following statement to parents and guardians through the school's notification system: 

"We are receiving notification from several students that there is a potential threat of school violence. We have currently issued a Code Blue for all schools. Code Blue places schools in Lockdown Mode. Students will not be allowed to leave campus, and visitors will not be allowed to enter any building at this time. Law enforcement is currently investigating this matter. We will send an update with further information." 

Atkins said that if the lockdown continues past dismissal for schools, students will be dismissed after the situation is cleared, and a bus route will begin at that time to ensure that students get home safely. Parents will also be able to resume usual car-rider pickup. 

Additional information will be sent out to parents and guardians about when students will be released from the lockdown. 

Cedartown and Rockmart police are working with Polk County Police, the Sheriff's office and the Federal Bureau of Investigation to track who sent out a threat against Cedartown and Rockmart High Schools.

Chief Jamie Newsome of the Cedartown Police Department said local agencies are cooperating together to find out who sent the threat

"We're doing everything legally possible," Newsome said. "We have all the investigative resources working on the situation right now."

Polk School District is on a Code Blue lockdown of all their campuses due to a threat sent to a student on an online account. According to a message received by the Standard Journal from WGAA 1340 AM's Andrew Carter, the threat came against both high schools.  

That threat read "I'm going to shoot your school up tomorrow around 1:30 so be ready" from a poster that went by "MAGG."

"MAGG" additionally said "In Polk County" when questioned by the student who received the post, and followed up "i'm shooting up cedartown high school and rockmart."

MAGG later stated "why did you screenshot" when the student asked for assistance in identifying the sender.

Rockmart Police Chief Keith Sorrells said that he's asked for the help of the FBI to track down the person who made the threat, but said the account that sent the message had since been deleted.

"They're working on it from their end," Sorrells said.

Both chiefs emphasized they felt there was no immediate threat to any of the schools, but have secured the schools and have law enforcement in every building as a safety precaution.
