After a robbery at an area Juice Stop, all Gretna schools were placed on lockout at around 11:40 a.m. Wednesday morning, our partners at the Omaha World-Herald report.
"As a precaution due to a robbery in town, all Gretna schools have been put in lockout," the text to parents read. "Check your email for more details."
During a lockout, classes proceed as normal but no one is allowed in or out of the building.
Following the robbery, deputies searched the area but were unable to find the robber.
