Officials say they are investigating a possible incident at Offutt Air Force Base and have closed the gate to STRATCOM out of "an abundance of caution."
According to a press release, a military working dog indicated a potential threat while making a routine vehicle inspection around 9:30 a.m. Thursday.
"Offutt personnel should expect delays while traveling on base until otherwise notified," the release said.
At around 11:15 a.m. the gates were reopened. Offutt officials say security forces took appropriate action and adhered to security protocols.
