Reigning 100m 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 offense, according to a police report obtained by the Associated Press. On Thursday, she ran in the opening round of the women’s 100m at US track and field championships in Eugene, Oregon. She has an automatic bye to the world championships in September in Tokyo as the defending champion.

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