Two 911 calls about a weapon and gunshots Tuesday morning led to a two-hour lockdown and closing of gates at Redstone Arsenal, but authorities said there was no evidence shots were fired.
Chris Colster, spokesman at the arsenal, said gates reopened but asked for "prayers for those involved in this situation".
Redstone Arsental spokesman Christopher Colster tells WAFF-TV that officials got reports of an active shooter on the base near Huntsville Tuesday morning. He says a "methodical investigation" was underway. But Colster would not say whether the active shooter report was part of that exercise, adding: "I really can't say at this point what happened".
In the hours following the warning, social media filled with reports, theories and well-wishes along with posts from anxious friends and family members of the approximately 30,000 government employees, civilians and contractors who work each day on the arsenal.
Law enforcement officials acted on a tip from a citizen to pursue the arrest of Sayyed who was living in an apartment near the University of Alabama- Huntsville. Sparkman Center and the surrounding roads remained closed as the building was searched. Officials there said the reports were unfounded.
According to WHNT, the base was supposed to have an active shooter training session this week, but authorities said the incident today is not a drill. An active shooter drill planned for Wednesday was canceled.
"Employees outside of the area of the incident, it can move freely on the base", she said.
The arsenal is located near the Tennessee border in northern Alabama, and more than 40,000 people work at the facility each day, Fox News reported. "I will continue to closely monitor and pray for a peaceful and quick resolution", she said.
"The important thing is everybody's safe", Ivey said.
