It happened at 6:07 p.m. in the 300 block of Manor Circle in Ridley Township.
Police say a 12-year-old girl was playing in her front yard when the man pulled up in a gray or silver older-model four-door vehicle.
The victim tells police the man said "Get in my car!" The girl yelled "no," and that's when her friends came around the side of the house. The man then drove away.
The suspect is described as a white man in his 30s with a gray, zippered, hooded sweatshirt. He also had a dark-colored mustache.
Anyone with information is asked to contact the Ridley Township Detective Bureau at 610-532-4002/4003.
