Meet Li Xu, a Chinese "army major" who cheated a strings of girls by disguising herself as a man and proposing marriage:
She was arrested after Liu Lian, of Datong city, Shanxi province, reported she had been cheated out of £11,000 by an army major named Li Zhanyu who she had met on the internet. [...]
Liu Lian said: "He said he wanted to date my daughter, but first needed money to break up with his current girlfriend. He also promised to find my daughter a good job."
But, after Liu wired the money, Li disappeared from her life. [...]
Police thought he was a conman at this stage but their suspicions grew during questioning as they noticed his high-pitched voice and fair complexion.
A check-up by female police revealed Li to be a 25-year-old woman. She confessed she had cheated another two women with the same marriage con.
Li's scam lasted for two years ... and you'd think the, um, boobs would give it away sooner: Link
