Gunshots were fired at a military recruiting center and a Navy Reserve center in different parts of Chattanooga, Tennessee, late Thursday morning, officials and witnesses said.
One officer is “down” in connection with the shootings, Chattanooga Mayor Andy Berke told reporters. He was not specific about the officer’s condition.
Witnesses said a man sprayed bullets at the glass doors of a military recruiting center at a strip mall on Lee Highway, and the U.S. Navy tweeted Thursday that a shooting happened at a separate location — the Navy Reserve center on Amnicola Highway. The two sites are 7½ miles apart.
By 1:15 p.m., the “active shooter situation” was over, police tweeted.
There are no indications so far of any link to terrorism, two sources briefed on the case said.
Gina Mule, a server at a restaurant, said she saw a man who’d been in a silver convertible Mustang, firing a “high-powered rifle” at the recruiting offices at about 10:50 a.m.
She said she first heard “Pow, pow, pow!” She then went to a window, through which she said she saw the man firing shots.
“I don’t know how many shots he fired, but it was a lot,” she said.
