Olympic gold medal-winning U.S. women's goalkeeper Hope Solo was arrested early on Saturday morning on investigation of two counts of domestic violence assault, police told the Seattle Times.
Solo, 32, is being held without bail at the SCORE misdemeanour jail in South King County.
The goalkeeper, who won gold at the Beijing Olympics in 2008, allegedly got into an argument with relatives at a family party at the home she shares with her husband, former NFL player Jerramy Stevens, in Kirkland, Washington.
At some point during the altercation, according to police, Solo physically struck her sister and nephew.
"There were visible injuries on them," Kirkland police lieutenant Mike Murray told the Seattle Times.
Officers were called to the home because of an assault and a noise disturbance.
"There was a big party going on at her house. It was an out-of-control situation," Murray told the newspaper.
It is not Solo's first brush with domestic violence. Her then-boyfriend Stevens was arrested in November 2012 for allegedly assaulting Solo.
He was not charged and they were married the next day.
