The Pennsylvania teen who won the Fortnite World Cup last month — pocketing $3 million in the process — was “swatted” over the weekend during a livestream on Twitch, he said.

The criminal harassment tactic involves making a false report to police in hopes of getting a SWAT team to bust into a video gamer’s house.

“Well, that’s a new one,” Kyle “Bugha” Giersdorf told Twitch viewers on Saturday after the incident.

“They came in with guns, bro. They literally pulled up,” he said. “That’s scary…The internet’s f—ing crazy.”

Giersdorf, 16, was in the middle of playing “Fortnite Arena Trios” with some friends when he stepped away for several minutes to deal with the cops.

“I’ve been swatted,” the teen can be heard saying.

“Kinda wild,” he later tweeted.

Authorities in Upper Pottsgrove Township, where Giersdorf lives, could not immediately comment on the “swatting” call when reached by The Post on Monday night.

A police spokesman told ESPN that they had received a report from a person claiming to be the teen — saying he shot and killed his father and had his mother tied up in the garage.

The incident — while “scary” — hasn’t deterred Giersdorf from doing his thing. He was back on Twitch, a video game streaming platform, streaming his gameplay on Monday night.

“This guy is the real deal,” a user wrote on Twitter. “Get it champ.”

Another person jokingly said, “Don’t get swatted.”

The act has become commonplace in the video gaming world, but also dangerous.

A 28-year-old father of two was gunned down by cops in Kansas after a man in Los Angeles reported a fake shooting and hostage situation at his home. The person who swatted him, Tyler R. Barriss, was later charged and sentenced to 20 years in prison for the stunt.
