Reigning 100m world champion Sha’Carri Richardson was arrested last weekend for allegedly assaulting her fellow sprinting star partner Christian Coleman at an airport, it has emerged.

Richardson was arrested at Seattle-Tacoma International Airport last Sunday on a fourth-degree domestic violence offense, according to a police report obtained by The Associated Press.

The 25-year-old was booked into the South Correctional Entity in Des Moines, Washington at 6.54pm last Sunday and released at 1.13pm on Monday.

On Thursday, she ran in the opening round of the women’s 100m at the US track and field championships.

Richardson has an automatic bye to the world championships in September in Tokyo as the defending champion.

“USATF is aware of the reports and is not commenting on this matter,” USA Track and Field said in a statement.

Richardson’s agent did not immediately reply to an email request for comment.

The police report said an officer at the airport was notified by a Transportation Security Administration supervisor of a disturbance between Richardson and Coleman.

The officer reviewed camera footage and observed Richardson reach out with her left arm and grab Coleman’s backpack and yank it away.

Richardson then appeared to get in Coleman’s way with Coleman trying to step around her. Coleman was shoved into a wall.

The report later said Richardson appeared to throw an item at Coleman, which the TSA indicated may have been headphones.

In the police report, the officer said: “I was told Coleman did not want to participate any further in the investigation and declined to be a victim.”

Richardson won the 100m final at the 2023 world championships in Budapest and finished with silver at the Paris Olympics last summer, but won gold in the 4x100m relay.

She had a positive marijuana test at the 2021 US Olympic trials and didn’t compete at the Tokyo Olympics.

Coleman, 29, was the 100m world champion in 2019 and later served an anti-doping ban for missing drug tests.

He finished fifth in the men’s 100m final at the US track and field championships on Saturday.
