A court in Vladivostok sentenced former Interior Forces Major Igor Matveev to four years of imprisonment for beating a subordinate. Matveev denies wrongdoing and explains the prosecution as revenge for his disclosing large-scale violations in his military unit. In May 2011, Matveev published on YouTube a video address to Russian President Dmitri Medvedev and Prime Minister Vladimir Putin unveiling a corruption network in the army and alleging that soldiers in his military unit in Vladivostok are fed with canned dog food. Matveev was sacked from the army and prosecuted on battery charges. Later local prosecutors stated that their investigation showed that dog food had indeed been substituted for canned stewed meat to conceal a theft.
