PiS MP Dariusz Matecki was temporarily arrested for 2 months by court order. The National Prosecutor's Office's message revealed, among another things, the circumstantial grounds contained in the application for the arrest. The MP was expected to have belonged to the secret "Group Entry" on the Signal messenger. It was utilized to "warn each another about the actions of law enforcement agencies". The MP was besides expected to have cooperated with erstwhile Deputy Minister of Justice Marcin Romanowski, besides suspected in the case of irregularities in the Justice Fund. As "Gazeta Wyborcza" writes, their conversations, in which they discussed tactics in the investigation, lasted almost until Matecki was detained by the ABW.
