Army’s Redstone Arsenal on lockdown for ‘possible active shooter’

Testing platform, Redstone Arsenal, Huntsville, Alabama

(CNN) –A lockdown still is in effect for one Redstone Arsenal building where a possible shooter had been reported Tuesday morning, but an all-clear has been announced for everywhere else at the northern Alabama army post, facility spokeswoman Kim Hanson said.

Authorities are “still working on confirming the situation” at the post’s Building 5301, Hanson said.

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

The US Army’s Redstone Arsenal post in Huntsville, Alabama, was placed on lockdown late Tuesday morning because of a “possible active shooter,” the facility’s Twitter account said.

There were reports of a shooter at Building 5301 — the Aviation and Missile Command building — at the post’s Sparkman Center, Army spokeswoman Kim Hanson said.

“Installation is locked down. Run hide fight,” the post’s Twitter account said.

An Army email sent to facility personnel and relatives was more explicit, saying an active shooter was on Building 5301’s second floor.

“If you are not in the Sparkman Center, stay away from the area,” said the email, sent at 10:08 a.m. CT and obtained by CNN.

Post spokesman Chris Colster said he didn’t have any information about whether anyone had been injured or killed. An ambulance service has been sent to the facility, said Kristin Clark, a dispatcher for Huntsville Emergency Medical Services.

The FBI said its agents are headed to the scene. Base security personnel were working with the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives, Hanson said.

Alabama Gov. Kay Ivey said her office is being updated about the situation.

“I will continue to closely monitor and pray for a peaceful and quick resolution,” Ivey said on Twitter.
