The incident started around 7:30 p.m. when the two victims said they were taken in a white van while playing near 32nd and Diamond streets.
The girls told police that the suspects later let them go.
The victims also said that a 7-year-old boy was in the backseat of the van wearing tape over his mouth.
However, sources tell Action News that there are inconsistencies in the statements provided by the girls.
Police sources also don't believe there was a young boy inside the vehicle.
No arrests have been made and no further information was immediately available.
The girls are safe and are being interviewed by police.
Anyone with information is asked to dial 215-686-TIPS.
