The suspect - Robert Ashley - was taken into custody Friday.
Ashley faces sexual assault, robbery, and related charges for an attack on an 81-year-old woman last year.
On Sept. 20, police received the call of a rape on the 1300 block of South 51st Street.
The victim reported that she was sleeping in her second floor bedroom when she awoke to find an unknown male on top of her.
The suspect physically and sexually assaulted her until she was able to push him away, at which point he fled the scene.
The victim was taken to Thomas Jefferson University Hospital for minor treatment.
DNA evidence linked Ashley to the crime and officers arrested him at a home in Drexel Hill.
According to police, Ashley admitted in a statement to entering the home, stealing an undisclosed amount of money and sexually assaulting the victim.
