The head of the Polish Police does not believe that the detonation of the grenade launcher from Ukraine, which occurred on Wednesday, 14 December in the Police Headquarters, is the consequence of a mistake. He has large doubts about this matter, as he emphasizes in his conversation with "Rzeczpospolita". "There are many reasons why individual may have wanted to either discredit me, or harm me, or destruct the relations of Polish-Ukrainian services" - he emphasizes, reporting what steps against aggressive actions of Russians have taken, among others, since the beginning of the fresh phase of the war in Ukraine.
