The topic of this work is juveniles as perpetrators of criminal acts with reference to property crimes. The aim of the work is to gain insight into the characteristics of juveniles as perpetrators of criminal acts and their criminal acts, which causes delinquency and which ultimately affects the creation of criminality in adulthood, because knowledge about this phenomenon has a greater chance of preventing it. In explaining this phenomenon, risk and protective factors play an important role, which greatly help experts in determining treatment and prevention. The biggest role in Croatian legislation is played by the Law on Youth Courts, which defines minors as persons between the ages of 14 and 18. Studying various statistics in Croatia, it is noticeable that in the period from 2015 to 2022, the number of reported, accused and convicted persons decreases every year. Juveniles most often commit criminal offenses against property, and within that category they most often commit theft and aggravated theft, which are also in a downward trend in terms of the number of crimes committed. The most recorded criminal offenses are in the Zagreb police department, and the least in the Virovitica-Podravine police department. In the ratio of male to female offenders, male offenders are the most represented, but the number of female offenders has been increasing in the last few years.
