Radja Nainggolan, the ex-Belgium and Inter Milan football star, has been arrested in connection with a major cocaine trafficking investigation in Belgium. The arrest comes shortly after Nainggolan announced his return from retirement to join second-tier side Lokeren. Authorities conducted a significant operation that resulted in the raiding of 30 locations, leading to his detainment on drug smuggling charges. This comes as a shock to fans and the football community, given his prominent past as a Champions League player.
