Police had been probing the incident since Saturday when the woman, whose name is not being released, was found partially clothed on the Lehigh River canal towpath across from Brother Thomas Bright Avenue.
She claimed that a man punched her in the face and dragged her into an abandoned boathouse, restrained her and sexually assaulted her. She was subsequently found by passersby, who called police even though the woman did not want them to, police said.
Easton police Lt. Scott Casterline said police found inconsistencies in the woman's story as early as late Saturday night, but "because this person may have gone through a very traumatic event ... we continued to develop information."
Casterline said the woman is not facing charges at this time, but the possibility remains.
"We thought getting to the truth of the matter was more important because of the alarm to the public," Casterline said. "I'd rather have the public not fear for their safety than file a minor criminal charge."Police said the woman "made the story up for personal reasons," but they would not elaborate.
