The State Police, as part of an investigation by the Milan Prosecutor's Office, executed a European arrest warrant in Spain Friday for aggravated kidnapping resulting in death against the son of Alexandru Adarici, 54, a Ukrainian and Romanian national, a former banker and business manager who fell to his death on January 23 from a B&B on Via Nerino, Milan.

The 34-year-old son allegedly "participated" in his father's kidnapping to force him "to transfer 250,000 euros in cryptocurrencies." Investigations by Milan's Flying Squad and prosecutor Rosario Ferracane, as stated in a statement released by prosecutor Marcello Viola, "have established that the suspect, after convincing his father—a businessman who, along with him, is active in the finance and investment sector—to travel to Milan to attend a business meeting" in that building on Via Nerino, not far from the Duomo, "conspired in his kidnapping to force him to transfer €250,000 in cryptocurrencies." According to the investigations, the 34-year-old is also "responsible for the fall from the apartment window" of the former banker, also because his son was the only "person present in the room at the time" of that fall from the fourth floor.
