A British woman has been found guilty of using the date-rape drug Rohypnol (search) to rob wealthy men of their expensive clothes and accessories.

Prosecutors in London say the 37-year-old mother of two used the lure of sex to be invited back to plush apartments, where she drugged the men and made off with clothes, shoes and watches.

One film producer says he was targeted at a classy nightclub. He said he could barely remember the night, and woke up the next day partially undressed and missing an expensive Rolex (search) watch.

The woman could face life in prison when she's sentenced next month.

British authorities believe it's the first time a woman has been found guilty of using Rohypnol to drug men.
