A 52-year-old St. Johns County man was arrested on a charge of sexual battery late Tuesday afternoon.
Randy Gadson Sr. was found at his home by St. Augustine police and brought in for questioning. He was then arrested and booked into the St. Johns County jail, where he was being held with bail set at $502,500.
Deputies responded to a report of a sexual battery that occurred Tuesday morning at the victim's home. The victim said she had walked her children to the bus stop and returned to her apartment to find Gadson sitting on her sofa, according to deputies.
Investigators said Gadson followed the victim into her bedroom, where they said he pushed her onto the bed, punched her in the mouth and brandished a knife. He then threatened her, before sexually assaulting her, investigators said.
A relative of the victim arrived as Gadson fled out the door on foot, investigators said.
The victim was taken to Flagler Hospital, where she was treated and released.
The suspect was found at his home late Tuesday afternoon and arrested.
Deputies said the victim and the suspect knew each other.
