The Jefferson County Sheriff’s Office bomb unit was able to determine there were no explosives in some strange looking devices that were found near Southwest Plaza Thursday morning.

Deputies first got a call about the objects at around 10:30 a.m. They say they were found in the 18000 block of West Bowles Avenue and resembled robot heads.

The investigation prompted authorities to shut down Long Drive for a brief period of time, but it has since reopened.

Who left the devices in the area remains under investigation.
