Stepan Petrovich Beletsky (Russian: Белецкий Степан Петрович) (Chernigov, around 1872-Moscow, 5 September 1918) was a Ukrainian statesman in the Russian Empire and the Head of the Police Department and involved in scandals around Grigori Rasputin. In January 1914 he was appointed as senator in the State Council.
In 1894 he graduated in law at the University of Kiev, in the same year appointed as civil servant, responsible for art and printing. In 1899 he was appointed as governor of the Kovno Governorate in Lithuania; in 1904 he was transferred from Kaunas to Vilnius, in February 1907 in Samara, where he was appointed as vice-governor and applied the newly introduced land reforms by Stolypin. When Stolypin became prime minister, he invited Beletsky to become assistant director of the Department of Police (between August 1909 and March 1912). Beletsky became its director until 1915.
From October 1914 Beletsky exercised 24-hour surveillance of Rasputin and his apartment. Two sets of detectives were attached to his person; one was to act undercover. From 1 January 1915 modified reports from Okhrana spies – the "staircase notes" – had to provide evidence about Rasputin's lifestyle. They were given to the Tsar in an attempt to convince him to break with Rasputin.
On 25 March 1915 (O.S.) Rasputin left for Moscow by train, accompanied by his guards. On the next evening he is said, while inebriated, to have opened his trousers and waved his "reproductive organ" in front of a group of female gypsy singers in the Yar restaurant. Dzhunkovsky and Beletsky verified later that Rasputin never visited the Yar restaurant. Dzhunkovsky was fired in August and succeeded by Beletsky.
No entries exist after Beletsky lost his position as the Director of the Police. Also for Bernard Pares, it was taken that the police were the enemies of Rasputin, and that the many stories which reached the public were simply their fabrications.
