Thirty-six-year-old Rick Lopez of Castle Rock was arrested Tuesday during a traffic stop in Onondaga County, New York.
He faces one count of sexual assault, and one count of sexual assault on a child by a person in a position of trust.
Lopez was the coach of the Colorado Hoopsters before resigning during a tournament in Oregon last month. The team said only that he left for personal reasons.
A former player met with investigators and accused Lopez of misconduct, and the warrants were issued. Lopez has denied the allegations.
He's being held on $500,000 bond pending extradition.
