All gates are closed and locked and sirens have been heard alerting people to stay indoors.
Some vehicles are allowed to leave the base but no one is allowed to enter.
KTHV-TV reports this is not an active shooter situation or a drill.
A post on the base Facebook page reads:
“The base is on lockdown as of 11:45 a.m. this morning in the interest of protecting all base members and resources from a suspicious individual.
