Redstone Arsenal Lockdown Lifted After Reports of Active Shooter, 1 Day ...

Part of the US Army's Redstone Arsenal post in northern Alabama was on lockdown for hours Tuesday as investigators tried to investigate reports that a shooter was in one of the buildings.

The lockdown remained in effect for the post's Sparkman Center as of about 1 p.m. (2 p.m. ET) -- three hours after the initial alert -- the base in Huntsville said on Twitter.
But a wider initial lockdown, which had included the rest of the post and the neighboring Marshall Space Flight Center, had been lifted, Army spokeswoman Kim Hanson said.
