A residential road in northwest Hall County was closed due to a “possible explosive device in a vehicle” for almost three hours.

About half of Pine Circle Drive near McEver Road was shut down but has re-opened.

“The device appeared to be a modified, homemade grenade,” Hall County Sheriff’s Office Deputy Stephen Wilbanks said in a news release.

The device was found in the trunk of a rental car.

After further inspection, a Georgia Bureau of Investigation disposal unit told the Hall County Sheriff’s Office the device was an incendiary, or burning, device instead of something explosive. As of 5:15 p.m., the device had been made safe.

The Sheriff’s Office said there will be criminal charges.

Hall school buses were not able to take students who live in that area home, and administrators contacted parents to make other arrangements.
