Police in Warsaw are looking for people who vandalised two memorials by spraying the message “Slava UPA”. The incidents were later linked to similar acts in other Polish cities, including Gdansk. The inscriptions appeared on the monument to the Heroes of the Warsaw Ghetto at the POLIN Museum of the History of Polish Jews and on the monument to the Soldiers of the Polish People’s Army on the Skwer Więźniów Politycznych Stalinizmu. According to Warsaw police, officers worked at the scene on Saturday, including investigators from the investigative and investigative unit and a forensic technician. The investigation is ongoing, with police carrying out steps aimed at identifying and arresting those responsible. Earlier in the country, Gdańsk police detained a 17-year-old suspect accused of damaging memorials and promoting a totalitarian system. In the Tricity area, “Slawa UPA” messages were reported on seven sites, including monuments in Gdynia. The Jewish Historical Institute in Poland and the Ukrainian Embassy in Poland condemned the vandalism, calling it part of a broader information and hybrid warfare effort. The embassy also appealed to Ukrainians in Poland not to take part in such illegal actions.
