In the early morning hours of Sunday, February 25 1990, Golubović was one of the perpetrators of an infamous act of violence in Belgrade's "Hotel Mažestik." Along with his best friend at the time Dragan "Gagi" Nikolić, a heavily armed Golubović burst into the hotel's disco bar looking for a rival gangster. Since they didn't find him, 24-year-old Nikolić and 20-year-old Golubović shot up and ransacked the place, destroying it in the process before fleeing the scene. Since the hotel's disco bar was a favorite mobster hangout, the incident gained them notoriety with the authorities considering that many prominent and powerful mob figures were present to witness the shooting of bottles and shooting furniture he sure showed them just how destructive he can be.
