Bivšega policijskog upravitelja u Banjoj Luci i Sarajevu vlastodršci su krajem 1940. odabrali za ravnatelja zagrebačkoga redarstvenog ravnateljstva kao zamjenu za nepouzdanoga Josipa Vragovića. Svojim je iskustvom i oštrim pristupom prema neistomišljenicima političkoga poretka, prokušanim tijekom sedamnaestogodišnje policijske službe, trebao suspregnuti sve snažniju djelatnost komunističkih i ustaško-frankovačkih snaga u hrvatskoj metropoli neposredno pred početak ratnih operacija na ovim prostorima. U prilogu se nastoji približiti Vikertov profesionalni i privatni život uz iznošenje podataka o njegovoj povezanosti s onodobnim političkim strukturama, načinu ophođenja s protivnicima režima te najbližim suradnicima. Posebna je pozornost posvećena upravljanju policijom u Banjoj Luci, Sarajevu i Zagrebu, što je naposljetku i dovelo do toga da je samo nekoliko dana nakon uspostave Nezavisne Države Hrvatske postao jednom od za režim najnepoželjnijih osoba. Rikard Vikert (1889–1941) was the last chief of the Zagreb police before the beginning of World War II in this region. He remained at this post only for a short time. Despite this, immediately after the establishment of the Independent State of Croatia, he was declared one of the most wanted persons of the new regime. The reasons for this were related to his earlier policing activities, especially his performance as the head of the Sarajevo police (1935–1940), when he was responsible for the cruel treatment of political dissidents of the old Yugoslav regime. He was trained to perform police duties as early as the time of the Austro-Hungarian Monarchy, acting as part of the armed forces, i.e. the gendarmerie, immediately after the establishment of the Kingdom of Serbs, Croats and Slovenes. He was well-accepted in centralist circles because he voluntarily left the Austro-Hungarian army and joined the Serbian army at the very beginning of the Great War. In this way, he gained the trust of Belgrade’s political elites, which found him suitable for larger police tasks, due to the fact he was an educated officer. From 1923, he was employed by the Ministry of the Interior, and climbed the administrative ladder within the police apparatus. He experienced a professional zenith when he became the chief of the Zagreb police, where he tried to oppose the increasingly strong attempts of members of the Ustasha and communist movements to break the old order. After the entry of German forces into Yugoslavia and the proclamation of the puppet Independent State of Croatia, he and his associates fled Zagreb, trying to find refuge in Sarajevo. There, at the end of April 1941, he committed suicide while resisting an attempt of the Ustasha police to apprehend him.
