In Warsaw, the inscriptions "Glory to the UPA" appeared on the monument to the heroes of the Warsaw Ghetto near the Museum of the History of Polish Jews, as well as on the monument to the soldier of the first Polish army.
As part of the investigation in this case, law enforcement officers arrested a 17-year-old citizen from Ukraine. He was accused of destroying monuments and "propaganda of a totalitarian system". The boy is now under police supervision.
