Bucharest's crime rate is rather low in comparison to other East-European capital cities, with the number of total offences declining by 51% between 2000 and 2004.[8] In particular, levels of violent crime remain very low, with 24 murders and 1069 other violent offences taking place in 2004.[8] Although there have been a number of recent police crackdowns on organised crime gangs, such as the Cămătaru clan, organised crime generally has a reduced impact on public life. Petty crime, however, is more common, particularly in the form of pickpocketing, which occurs mainly on the city's public transport network. Additionally, confidence tricks such as the Maradona scam are sometimes common, especially in regards to tourists, even though the frequency of these tricks has declined in recent years. Levels of crime are higher in the southern districts of the city, particularly in Ferentari, a socially-disadvantaged area mainly inhabited by people of Roma ethnicity.
