His final European arrest occurred in Basel, Switzerland during a routine traffic check on 15 February 1983. However he managed to escape again within months, this time from Thorberg prison on 27 April. It is widely speculated that Ražnatović was closely affiliated with the Yugoslav security service UDBA throughout his criminal career abroad. He had convictions or warrants in Belgium (bank robberies, prison escape), the Netherlands (armed robberies, prison escape), Sweden (20 burglaries, 7 bank robberies, prison escape, attempted murder), West Germany (armed robberies, prison escape), Austria, Switzerland (armed robberies, prison escape), and Italy. Thirty-one-year-old Ražnatović returned to Belgrade in May 1983, continuing his criminal career by opening a number of illegal businesses. In November 1983, six months after his return, a bank in Zagreb was robbed with the robbers leaving a rose on the counter – allegedly Ražnatović's signature from his Western European robberies. Looking to question Ražnatović about his whereabouts during the robbery, two policemen, members of the Secretariat of Internal Affairs' (SUP) Tenth department from the Belgrade municipality of Palilula, showed up in civilian clothing at his mother's apartment on 27 March Street in Belgrade. Ražnatović happened not to be home at the moment, so the policemen introduced themselves to his mother as "friends of her son looking to return a cash debt they owed him" and asked the women if they can stick around in the apartment to wait for him to return. His mother phoned him to say that two unknown males waited for him, which was enough for him to clue in that something's amiss. He showed up with a revolver and proceeded to shoot and wound both policemen – shooting the first one on the spot and the other in front of the apartment building as he tried to flee the scene. Ražnatović was detained immediately; however, barely 48 hours later, he was released. The occurrence made it clear to all observers, especially his criminal rivals, that he enjoyed protection from the highest echelons of the political leadership in SFR Yugoslavia. He spent the mid-1980s running a disco club, "Amadeus", together with Žika Živac and Tapi Malešević. Located in the Tašmajdan neighbourhood, the club was reportedly another perk of their contractual work for the security service. Furthermore, Ražnatović could be seen riding around Belgrade in his pink Cadillac and gambling on roulette in casinos all over the country, from Belgrade and nearby Pančevo to Sveti Stefan and Portorož.
