HUNTSVILLE, Ala. — A lockdown at the U.S. Army’s Redstone Arsenal post in northern Alabama was lifted on Tuesday after reports of a possible active shooter.
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 the building’s second floor.
All of Redstone’s perimeter gates were closed, and staff members were told to shelter in place, Hanson said.
At 12:30 p.m. CDT, the lockdown was lifted, though officials asked that movements be limited.
An ambulance service was sent to the facility, said Kristin Clark, a dispatcher for Huntsville Emergency Medical Services.
The FBI said its agents are headed to the scene.
The incident remains under investigation.
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.
