HUNTSVILLE, Ala. – The US Army’s Redstone Arsenal post in northern Alabama is on lockdown because of a “possible active shooter,” the facility tweeted Tuesday.
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.
An Army email sent to facility personnel and relatives was more explicit, saying an active shooter was on the building’s second floor.
“If you are not in the Sparkman Center, stay away from the area,” the email, sent at 10:08 CT and obtained by CNN, reads. “… this is an initial report, 911 has been called, more to follow.”
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.
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.
