The woman, who is reported to have previously worked as a prostitute, has been in custody since July 13th, after one of her victims recognised her at Graz train station and alerted police.
Two men have come forward to say they were robbed by the woman, who called herself ‘Susie’, or ‘Susa’. In both cases the men met her near to the train station, and she asked them if she could spend the night with them.
She then poured drops, containing chloral hydrate or a similar sedative, into their coffee or beer and once they had dozed off she took their debit cards and cash.
"She admits to having robbed another ten people in the same way. She bought two bottles of the 'date rape' drug at a Budapest market, and when we arrested her we found both bottles were empty,” police detective Mario Hartmann said.
A 61-year-old man who she robbed may have been overdosed with the sedative as he became unwell and had to spend a week in hospital.
It is thought that the woman may have succeeded in stealing thousands of euros. Police have released a photo of her and have asked any other possible victims to notify them.
