The police officer who took down the Allen, Texas mall gunman made a panicked call for backup — pleading for “everybody” — moments before he encountered the suspect and shot him dead.

As he rushed to the H&M store at the Allen Premium Outlets Saturday, the hero officer tried his best to relay the chaos outside the mall where a man in his 30s opened fire, killing eight people and injuring seven others, including children, audio of the call to the Allen Police Department reveals.

With dozens of gunshots ringing out, the officer urged his fellow cops to get to the scene as fast as they could to help him take down the gunman, the New York Post reports.

About two minutes after urging for backup to arrive, the officer was successfully able to take down the shooter, telling his colleagues: “I got him down,” according to the audio obtained by the Daily Mail.

The officer, who has not been publicly identified, was initially at the mall for an unrelated call, Allen Police Chief Brian Harvey told reporters.

“He heard gunshots, went to the gunshots, engaged the suspect, and neutralized the suspect,” Harvey said.
