PHILADELPHIA — Philadelphia police say they’re looking for three masked men who reportedly abducted a 16-year-old girl then sexually assaulted her in an abandoned building.

The girl tells police the men were wearing ski masks when they forced her into a small car in the city’s Frankford section just after 6:45 p.m. Thursday.

Police say the girl was able to run away after the assault and contact a relative.

Medics treated the girl at the scene.
