Reigning 100-metre world champion Sha’Carri Richardson was arrested last weekend for allegedly assaulting her boyfriend at the Seattle-Tacoma International Airport.

Richardson was arrested Sunday on a fourth-degree domestic violence charge, according to a police report obtained by The Associated Press. On Thursday, she ran in the opening round of the women’s 100 metres at the US Track and Field Championships in Eugene, Oregon. As the defending champion, she has an automatic bye to the world championships in September in Tokyo.

The 25-year-old Richardson was booked into the South Correctional Entity (SCORE) in Des Moines, Washington, at 6.54 pm last Sunday and released Monday at 1.13 p.m.

“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 Richard’s son and her boyfriend, sprinter Christian 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.
