A Sydney woman who claimed she had narrowly escaped being abducted by a carload of men while the public watched has been charged after she allegedly made up the story.

The woman, who identified herself only as Aida, stood with police last week and told of her terror when she was grabbed by a man near Liverpool train station on the afternoon of January 13.

She also spoke of her disappointment that none of the "dozens" of people who had been near her at the time had come to her assistance.

"Of course I understand that you want to be safe yourself but there were people in groups," she said. "This is what upset me; they weren't alone."
