A woman in her 30's claims she was sexually assaulted in the car by a police officer.
Police sources say the two encountered each other around 4:00 a.m. at a bus stop on Cobbs Creek Parkway near Market Street.
They say the woman claims she asked for a ride to the 69th Street Terminal.
Instead, the woman told investigators the officer drove her a block away to a parking lot at a recreation center.
That's where she claims he demanded she perform a sex act.
She says she complied and the officer then drove her to 69th Street.
SEPTA confirms she ran to a SEPTA police officer and reported what had happened.
The SEPTA officer drove her to the Special Victims Unit.
SEPTA also says it is preserving video surveillance and will turn it over to the Philadelphia police if requested.
The Philadelphia police officer is assigned to the 18th district and was on the midnight to 8 a.m. shift.
Action News is withholding his name, but sources say he has a record of complaints filed against him by other women.
The police Internal Affairs Unit is handling the investigation.
Sources say they have requested a search warrant for a DNA sample from the officer.
