The most common criminal act in the world and there fore also in Croatia are acts of property offenses and through this work we are going to process criminal act „Theft“ and „aggravated theft“ and also criminal act of property offenses with elements of violence that includes criminal act „Robbery“, „Robbery theft“, and „extortion“. We will primarily be based on criminal offenses „ Robbery“, committed by individuals but also as a form of organized crime group activity. Latterly, criminal acts of property offenses with elements of violence are not a rarity, but when they are made by a group then the object of attack in most cases are institutions that can obtain substantial material gain in addition to the above crimes we mentioned earlier. The objects of attack are often a monetary institution (bank, currency exchange office, ... etc.), it is also common that vehicles carrying money or securities are intercepted and that is why they are provided with security personal and high grade technical protection. Further in this work we will process and analyze an event of multiple criminal acts „robbery“ by an organized criminal group in which „a prominent member“ was the an security personal who was providing physical security in a bank that was also the object of attack.
