Police say they have no leads into the investigation of last Monday's sexual assault of a female student in her apartment on the 4000 block of Spruce Street.
Philadelphia Police Special Victims Unit Capt. John Darby said detectives are still reviewing surveillance footage of the surrounding area to try to pinpoint a suspect.
He also said forensic evidence found at the scene has not led to any conclusive leads.
Detectives believe the suspect entered through the back door of the apartment. It is not known if the door was locked, and there were no signs of forced entry.
The investigation is still ongoing and will likely remain active for the foreseeable future.
