Picabo Street called police Dec. 23, saying she "had got into a fight" with her father, according to a probable-cause statement filed with the Summit County jail.
"Picabo stated that during the fight, Roland pulled her hair," an officer wrote in the jail statement. "Picabo stated that during the fight, she pushed Roland down the stairs and locked him in the basement before she called dispatch."
Roland Street told police that before the fight, he was trying to leave the home and "bumped his car into the house." His daughter yelled at him, Roland Street told police, and a physical fight ensued inside the home.
The father also reported that Picabo Street pushed him down the stairs, and he told police that he "fell down two flights of stairs and may have hit his head." A responding police officer noticed Roland Street had cuts on his elbow and neck, according to the report.
Picabo Street's three children witnessed the fight, according to police.
The woman posted bail and is expected in court Feb. 16 for a pretrial hearing. She has pleaded not guilty to the charges.
No charges had been filed against Roland Street as of Wednesday.
Picabo Street, a part-time Park City resident, won a gold medal in Nagano in 1998 and was a Fox Sports analyst for the 2014 Olympic Games.
