- On Monday, we initiated an investigation, and in the course of this investigation, which lasted several dozen hours, we obtained evidence indicating a very high probability that the direct perpetrators of these acts of sabotage of a terrorist nature were two Ukrainian citizens - said Przemysław Nowak at a press conference.

- The evidence we have includes primarily the results of on-site examinations of the event locations [...] this evidence also includes witness testimonies [...] telecommunications data [...] and also recordings from secured surveillance - he continued.

- Today, the prosecutor signed the decisions to present charges against these two men. In the briefest terms, these charges concern the commission of acts of sabotage of a terrorist nature on behalf of the intelligence services of the Russian Federation against the Republic of Poland on November 15-16 this year - he went on to say.

- These charges relate to both incidents we have reported on - he added.

- This charge is qualified cumulatively under three articles: an article concerning a form of espionage in the nature of sabotage acts for a foreign intelligence service, causing a disaster threat in land traffic, and the use of explosives. This is an offense punishable by life imprisonment - he emphasized.

- The prosecutor has the material and has prepared a decision to present charges against these two men, however, it is not possible to carry out procedural actions with them, as they fled Poland during the night from Saturday to Sunday - he stressed.
