Police received reports of an elderly woman being raped at the Autumn Leaves Memory Care Center back in February and the 61-year-old Reed, who works as a caretaker at the facility, was named as the suspect.
The Northern Oklahoma Violent Crimes Task Force arrested him on Tuesday in Claremore.
According to the Tulsa County Jail website, Reed faces one charge of first degree rape while the woman was mentally incapacitated or of unsound mind.
The other charge is listed as rape by force or fear.
Reed is due in court April 12.
