PHOENIX (AP) -- Authorities say a man is in custody for allegedly sexually assaulting a 15-year-old girl in Phoenix.
Maricopa County court records show 19-year-old Derrick James Shepard was arrested Wednesday.
Phoenix police say Shepard is jailed without bond because of the nature of the alleged offense.
He's being held on suspicion of sexual assault and sexual conduct with a minor.
The girl told police that Shepard engaged in sexual conduct with her against her will last weekend.
She also claims Shepard physically prevented her from stopping the act.
Police say Shepard knew the victim was a minor.
It was unclear Thursday if Shepard has a lawyer yet.
