The possibility of suspicious materials in a shed in DeKalb County, following multiple arrests in a residence on Chamblee Tucker Road, necessitated a call to the bomb squad.

DeKalb police served three arrest warrants Tuesday on a home in the 4300 block of Chamblee Tucker Road and in the process discovered unknown materials in an out building, according to spokeswoman Mekka Parish.

“The bomb squad was called as a precaution,” she said.

Parish said the arrest warrants were executed and there is a fourth person in custody.

No other information was immediately available.
