LINCOLN, Neb. (AP) — A Lincoln man has been charged with sexual assault after a woman staying at his home claimed he raped her.

43-year-old Ricky Lee Jackson was charged Wednesday with first-degree sexual assault. He remained in custody Thursday.

Police say Jackson allowed a woman he knows to stay at his apartment in November after she had gone out drinking with her friends. The woman told police she fell asleep several times and continuously woke up to Jackson performing sexual acts on her.

Officer Michelle Jochum says the woman reported the alleged sexual assault the next morning. Police say they interviewed Jackson about the incident Tuesday after months of investigation. He told officers he didn’t hear the woman tell him to stop.
