Decatur schools continued to operate “as normally as possible with additional security precautions in place” after new bomb threats, the district said Friday afternoon.

Bomb threats targeting two schools were similar to those received around the country this week, Decatur police said.

“We are monitoring the schools as staff work to operate as normally as possible,” police Lt. Jennifer Ross said. “We are investigating these threats in conjunction with other local, state and federal agencies.”

Police did not say which two schools were targeted.

After-school activities and dismissal proceeded as usual Friday, school officials said on Facebook.

The threats were the second in as many weeks for Decatur schools.

Multiple businesses and government buildings across metro Atlanta were the targets of emailed bomb threats Thursday afternoon, police said, believed to be in line with hoaxes that were received in cities across the country.

Agencies in Atlanta, as well as Cobb, Gwinnett and Forsyth counties, investigated the validity of the threats, but none were deemed credible. Some authorities said the threats were tied to ransom demands through Bitcoin.

On Nov. 27, students spent most of the day on lockdown after threats were made against multiple Decatur schools.
