On 14 April 2015 a Moscow court sentenced Georgy Alburov, an employee of Navalny's Anti-Corruption Foundation, to 240 hours community service for the alleged theft of a painting, entitled “Bad and Good Man”, by a street artist in the city of Vladimir, 200 km east of Moscow. Alburov, who has made a reputation for exposing the wealth of highly-placed government officials, maintains his innocence and claims the accusations against him were politically motivated. The New York Times commented: ‘In his closing remarks at the trial, Mr. Alburov insisted that the prosecution was politically motivated, and related more to his research into the ill-gotten gains of senior officials, than any desire to protect Mr. Sotov’s street art.’ The officers seized the painting described by the New York Times as ‘a grimy piece of street art’, in a search of Navalny's apartment. The artist, Sergei Sotov, was reported as saying he had no claims against Navalny or his associates.
