Possible active shooter at Redstone Arsenal in Huntsville, Ala

More than 35,000 people work at the 30,000 acres Redstone Arsenal.

Officials at Alabama military post say a lockdown has been lifted after initial reports of active shooter.

The base has called off a drill on how to respond to an active shooter because personnel learned "everything they need" on Tuesday, Holiday said.

Officials are allowing traffic onto and off the base, post spokesman Chris Colster said. Installation is locked down.

This morning, a potential active shooter incident occurred at Redstone Arsenal, in the Sparkman Center. No one is in custody at this time, Colster said.

The Arsenal is a garrison for a number of tenants including the United States Army Materiel Command, Army's Aviation and Missile Command, the Missile Defense Agency of the Department of Defense, and NASA's Marshall Space Flight Center.

The Army post has a government and contractor workforce that averages 36,000 to 40,000 personnel.

After a tweet advised workers of a possible active shooter and told them to "run hide fight" many people took to social media to offer their prayers and await updates.

In the press conference that followed the arrest, Madison County Sheriff Blake Dorning specifically mentioned Redstone Arsenal.
