The call came in at 1:15 p.m. ET, and the Nashville Fire Department dispatched three EMS units to the scene.

The gunman, who police are describing as a local 51-year-old white male, was carrying a gun, hatchet and pepper spray when he entered the theater. Three victims, two women and one man, were injured by pepper spray, and the man also suffered superficial wounds to his arm from the hatchet, the Nashville Fire Department confirms. The shooter tried to exit through the back of the theater, where he was shot.

CNN reports that moviegoers were seeing Mad Max: Fury Road, starring Charlize Theron and Tom Hardy.

As of Wednesday evening, the theater was still closed for an unknown amount of time, as "a significant discharge of chemical spray," was released, according to Dan Aaron, Public Affairs Manager for the Nashville Police Department. Aaron also told reporters that a satchel, which officers believe was the shooter's, still needed to be addressed and eventually detonated.

CBS News reports that police engaged with the shooter, who was wearing a surgical mask, and that a police spokesperson said the officer was brave and saved a lot of lives. Officers are trained for a situation like the one that occurred today in Antioch, and this particular officer did whatever he needed to do in order to rescue anyone inside.

This shooting comes less than two weeks after a gunman opened fire during a screening of Trainwreck in Lafayette, Louisiana, on July 23, killing two and injuring nine. The gunman, John Russell Houser, shot himself and died in the theater.

Trainwreck star Amy Schumer and her cousin, Senator Charles Schumer, held a press conference about gun violence in New York City on Monday. "No one wants to live in a country where a felon, the mentally ill or other dangerous people can get their hands on a gun with such ease," she told reporters. "The critics scoff and say, 'Well, there's no way to stop crazy people from doing crazy things,' but they're wrong."

Schumer has vowed to keep fighting for this cause, which can be heard in the video below. "Preventing dangerous people from getting guns is very possible," the actress added. "These are my first public comments on the issue of gun violence, but I promise you they will not be my last."
