Pickpockets in Warsaw are artistic and numerous, and are especially active on crowded buses and subways and at train stations. The number 175 bus that runs from the airport past major hotels and the “Russian market,” a popular tourist spot, has a high number of victims. Thieves also work trains that run both within the country and to other countries, spraying dozing travelers with a knock-out drug, then robbing them. In Krakow’s historic Rynek market area in the center of town, the outdoor restaurants are common targets for thieves snatching purses or briefcases placed under the tables.
