When he called her back and asked her for the money she started threatening him. Someone she knows sent him an email soon after she left, showing snippets from her 'Facebook' which contradicted a lot of what she had told him. When he confronted her she told him that she would send a message to the medical board (he's a doctor) and tell them that he had accessed her information without her permission (which is ridiculous) but that he had also given her pills intended to drug her (he had given her ibuprofen for a headache).
What can he do? I'm not sure if the police would care or even listen to him- his English is not that good when he's flustered. What about the accusations? The money's insignificant compared to what accusations like that could do to his career.
