Troubling new video shows a cop with a Taser intimidating a group of students outside a prestigious Brooklyn high school, threatening one of the teens: “You wanna ride the lightning?”

The footage, posted to YouTube on Saturday, shows the cop and his partner moving the gaggle along in front of Midwood High School, Gothamist reported.

One officer has his baton out, and lightly pushes one of the students ahead of him.

When she complains, “Don’t touch me,” he answers twice, “What are you going to do about it?”

As the kids continue to walk away, he draws his Taser.

“Pick that s— up again,” the officer says. “You wanna ride the lightning?”

When the students cross the street, he adds: “You better walk away.”

The video was filmed March 16 by CUNY associate professor Alex Vitale who told the site, “I see officers aggressively dispersing students from Midwood all the time,” although never before with a Taser.

The NYPD said the video is under review, the site reported.

The NYPD patrol guide states Tasers should only be used against aggressive, resisting individuals, and generally not against children — though the guide does not specify when it is appropriate to only threaten someone with a Taser.
