This market will resolve to "Yes" if Aleksandar Vučić is arrested or detained by law enforcement by the specified date, 11:59 PM ET. Otherwise, this market will resolve to "No". Temporary holding at a detention facility while awaiting a judge’s decision on whether to grant a detention warrant qualifies, so long as they are held by law enforcement in an official capacity during that time. A qualifying arrest/detention includes: * Being taken into physical custody by law enforcement authorities (including federal, state, local, military, or international law enforcement) * Voluntarily surrendering to law enforcement authorities in response to an arrest warrant * Being formally booked or processed following detention * Being handcuffed by a state authority and taken to a police station * Surrendering at a police station or courthouse with their attorney * Being placed under house arrest or electronic monitoring The following scenarios will NOT qualify as an arrest/detention * An arrest warrant being issued but not executed * Being questioned or interviewed without arrest * Being named in an indictment without arrest The primary resolution source for this market will be official information from the arresting government and law enforcement; however, a consensus of credible reporting may also be used.
