Two women have been arrested for pickpocketing several victims who had come out of a currency exchange office near the Geneva main train station.
Police say they stole a significant amount of money.
One victim says she lost thousands of UK pounds and another thousands of francs two weeks ago.
According to the police, the thieves used distraction techniques to pickpocket the cash, such as pretending to accidently spill a liquid on the target.
Using CCTV images, two women in their twenties are now in custody.
Police are urging people to be careful if they have a large amount of cash on them.
