Bratislava is generally a safe city to visit and most visitors will experience a trouble-free holiday. However, it is wise to be careful of personal possessions, particularly in popular tourist areas and on public transport, due to increasing incidents of pick-pocketing and bag snatching.
Do not leave precious things in a car. Even very popular parking sites can not be considered safe your possession inside the car.
There are some useful notices from the report of the Overseas Security Advisory Council (a U.S. Government inter-agency Web site managed by the Bureau of Diplomatic Security, U.S. Department of State): The local pickpockets are professional and most active during the summer months. They tend to utilize distraction techniques to confuse their target, and prefer crowded locations such as shopping centers, tourist sites, markets, public transportation, hotels popular with foreigners, and on the night trains to Prague and Warsaw.
The rate of automobile theft, which is also connected to organized crime, is very high in Bratislava. Many stolen vehicles are quickly transported out of the country for resale in neighboring countries. Preferred targets for the auto thief are high-end European and American vehicles. The use of a car alarm system or anti-theft device is strongly encouraged.
