He was supposed to document military transports. A 40-year-old man detained by the Internal Security Agency was taken into custody

The court imposed a three-month arrest on a 40-year-old man detained by the Internal Security Agency. A Pole suspected of reporting his readiness to act for foreign intelligence was supposed to document military transports, said Minister Tomasz Siemoniak.

When asked by PAP, the minister coordinator of secret services noted that this was a new case.

“During the searches, evidence was secured of the suspect's collection of materials documenting, among others, railway transports of military equipment,” the minister said in a Saturday entry on the X platform.

Siemoniak noted that the court decided to arrest the 40-year-old Polish citizen on Saturday.

“On Saturday, December 20, 2025, the court applied a preventive measure in the form of pre-trial detention for a period of 3 months against a 40-year-old Polish citizen who was charged with reporting his readiness to act for a foreign intelligence service (Article 130, paragraph 3 of the Penal Code). This person was detained as a result of the actions of the Internal Security Agency,” the minister said in the entry.

When asked by PAP about the detention of the 40-year-old, the minister's spokesman, Jacek Dobrzyński, explained that due to ongoing operational and investigative activities, he could not inform about other details of the case at this stage.

The deputy district prosecutor in Bydgoszcz, Agnieszka Adamska-Okońska, told PAP on Saturday that the prosecutor accused the man detained on Thursday by the Internal Security Agency of collecting and recording materials documenting, among others, railway infrastructure and transport of military equipment by rail, in order to act on behalf of foreign intelligence.

When asked, she said that the investigation into a 40-year-old man who lives in Tricity and was arrested there – previously convicted for common crimes – is being conducted at the Bydgoszcz prosecutor's office, because it was in this area that his documentation of the railway infrastructure was revealed. During the proceedings, investigators found that he documented railway transports of military equipment in northern Poland, noted prosecutor Adamska-Okońska. After presenting the charges on Friday, at the request of the prosecutor, the court arrested the man on Saturday for three months, she said.

Another investigation conducted so far in a similar case concerned the so-called cameramen who tried to track trains carrying weapons and humanitarian aid to Ukraine with the intention of derailing them. It has been conducted since March 2023 by the Internal Security Agency under the supervision of the Lublin branch of the National Prosecutor's Office.

It concerns the activities of an organized criminal group, consisting of at least 30 people, for the benefit of the Russian secret services, which carried out espionage, sabotage, sabotage and propaganda activities against Poland on the territory of the Republic of Poland. In 2023, the Internal Security Agency detained a total of 16 members of the group – 12 citizens of Ukraine, 3 of Belarus, 1 of the Russian Federation, and based on the collected materials, the court sentenced all 16 defendants.

Recently, at the beginning of December, the Internal Security Agency reported that an arrest warrant had been issued for a person suspected of organizing this group. The wanted person is a Russian – Michail Mirogrodskij, who, according to investigators, commissioned by the FSB, had, among others, directly assign espionage tasks to group members, provide them with implementation instructions and manage Telegram accounts used for communication within this group.
