Investigators said the girl was blindfolded, forced to change out of her clothes and made to hide under a bed after being taken from her classroom Monday morning.
A passer-by found her early Tuesday shivering under a piece of playground equipment at a park in Upper Darby, just outside Philadelphia.
According to police, the woman claimed she was the girl's mother and was coming to take her to breakfast. After leaving school, police said the woman and the victim walked a few blocks to a home where a man was waiting.
Authorities believe the victim was targeted but have not disclosed a motive. School officials said personnel did not follow proper procedures before releasing the child.
