Uriel Garcia, 18, and Mafe Jose Cruz-Berula, 19, were arrested at a Greeley apartment complex Sunday night.
Police say four juvenile girls, who lived in the same complex as the suspects, were reported missing Sunday after failing to arrive at a friend's apartment unit.
According to Greeley police, the four girls met up with Garcia and Cruz-Berula and returned to the suspects' apartment where one of the girls was sexually assaulted.
Police also found evidence of alcohol in the home.
Cruz-Berula is facing child sexual assault charges as well as a felony charge of contributing to the delinquency of a minor. Garcia was only charged with contributing to the delinquency of a minor, a class 4 felony.
