On Sunday morning, you might see a lot of police and emergency vehicles swarming Perimeter Mall.

Do not panic.

It is just a test.

The Dunwoody Police Department says the mall has "graciously" allowed a training exercise from 7 to 11 a.m., before the shopping hub opens for business.

"As a result, you may see a large number of emergency vehicles, observe police activity and hear noises associated with a police operation at Perimeter Mall early Sunday morning," Sgt. Aaron Belt said in a news release.

Check the department's social media channels for updates and contact Belt with any questions at aaron.belt@dunwoodyga.gov or 678-382-6933.
