The Koszalin District Prosecutor's Office has initiated an investigation into Andrzej K., who posted social media messages praising a recent attack in Krakow. He suggested that further attacks could occur and claimed to belong to a trained militant group. Although he admitted to making the posts, he denied any intention to carry out an attack. He faces charges for disseminating information about alleged attacks and publicly praising a crime, which could lead to a 15-year prison sentence. The Koszalin District Court has approved his temporary detention.
