A cop sparked outrage in suburban Atlanta by aiming his gun at five young teens and keeping it unholstered for more than four minutes — with a growing band of angry onlookers screaming at him to “let them babies go.”

The officer drew his gun on the youngsters — who had been spotted with what turned out to be a realistic-looking BB gun — making them stand for several minutes with their hands in the air in Jonesboro.

It soon led to a large group of onlookers screaming abuse at him Monday — at the same time protests continued over the deadly police shooting of Rayshard Brooks at a Wendy’s drive-thru just 15 miles away.

“Sir, please — please let them babies go,” one woman begged the Clayton County cop in a video posted to social media.

“Why you have to have a gun out? They kids. They f–king kids!” a woman screamed at him, as the crowd grew both larger and angrier.

One man yelled that the youngsters — still stationary with their hands up — were “probably not even 16, 17,” saying, “They’re not even legal yet.”

Police bodycam footage showed the officer telling the kids to “relax” as he still aimed his weapon at them, insisting, “Please, I don’t want to hurt one of y’all.”

He also called for backup for a “crowd forming on me,” telling the onlookers he needed his gun to “stay safe” as it was “one against five.”

After initially aiming straight at the teens, the officer dropped the weapon to the “low ready” position, he said in his police report, keeping it out for more than four minutes, the bodycam shows.

He finally put away his weapon when a fellow officer arrived.

After the officer patted them down and found nothing, the teens took him to where one of them admitted throwing a BB gun that was mistaken for a real handgun when they had earlier been in a store, the footage shows.

“You’re not in trouble,” he told them at the time, saying his only concern was they “could get hurt.”

“I got kids just like you,” he told them.

His chief, Kevin Roberts, said drawing his weapon was the right thing to do given that the 911 call said one of the teens was armed.

Roberts also praised the officer for being “calm” while everyone around him “was a storm,” jumping to wrong conclusions before the department was able to explain its actions.

“Police officers make mistakes, they make bad decisions — this was not one of those times. He was doing his job,” Roberts insisted.
