Sha’Carri Richardson forcefully shoved her boyfriend multiple times during a dispute at an airport last month before appearing to throw something at him, new video, obtained by TMZ Sports, shows.

The incident took place on July 27 at Seattle-Tacoma International Airport in King County, Wash. … and you can see in surveillance footage we just got, the Olympic gold medalist appeared furious with her partner, Christian Coleman.

In the clip, Richardson is spotted grabbing Coleman’s backpack, before getting in his face.

Port of Seattle Police documents state once Richardson talked to officers, she told them the tiff started because Coleman had taken her electronic headphones.

“Richardson advised she did not assault him in anyway,” police wrote in the docs, “and the dispute was only a verbal argument.”

Authorities said they arrested Richardson after reviewing the surveillance video. She was ultimately booked on a charge of fourth-degree assault … and spent roughly 18 hours behind bars.

On Monday, Coleman — one of the fastest sprinters in the world — defended Richardson’s behavior … telling reporters, “it was a sucky situation all around.”

“I don’t feel like she should have been arrested,” he said. “People have emotions and stuff like that, and she has things she gotta work on for herself. So do I, so do you.”
