February 27 in Russia, a Polish journalist Tomáš Maceičuk was detained in the town Mytishchi, near Moscow, RIA Novosti reported.
According to the agency, certificates of merit and symbols of "Ukrainian nationalist battalions" that the journalist had with him were found.
The Polish journalist faces deportation - he is already being taken to court.
In the spring of 2017, on the Russian NTV channel Maceičuk called the Soviet soldiers who participated in the Great Patriotic War, the "Red Fascists". In response, Russian political scientist Ruslan Ostashko started a fight with him.
According to the journalist, law enforcement agencies have been following him for a long time.
“And the last straw was the statements about the shooting in the Donbas. He did not say which way he shot, I note it. But he admitted that he had shot. This was the last straw and they decided to bring this case further and start to restore order,” Russian political scientist Ruslan Ostashko said.
Russian media reported that Maceičuk was detained for violating migration legislation.
Earlier, Russian journalist Viktor Maistrenko said that Russian opposition politicians do not have a clear position on the Crimea and the Donbas, which is in the hands of the Kremlin
