On 16 December 2025, the Agency for Internal Security (ABW) reported the detention of Matthew W., a student of the Catholic University of Lublin (KUL), who is suspected of preparing a mass assassination at one of the Christmas fairs. This information was provided on the X platform (formerly Twitter) by Jacek Dobrzyński, the press spokesman of the Minister of Special Services Coordinator.
Detention details
According to the ABW communication, Mateusz W. planned to launch an attack using self-made explosives. The man had previously gained knowledge of the production of such materials, and his goal was to intimidate many people and support the Islamic State – a terrorist organization. Additionally, the suspect considered joining a terrorist group in order to obtain assistance in carrying out his intentions.
During their operations, ABW officers secured data carriers and Islam-related items. The court decided to apply to the detained temporary detention for a period of three months. The investigation in this case is carried out by the Szczecin delegation of ABW under the supervision of the local branch of the National Prosecutor's Office in Szczecin. As highlighted, the case is developmental, which means that further findings may arise
Background and Background
The Catholic University of Lublin, at which Matthew W. studied, is one of the oldest Catholic universities in Poland. Information about the detention of the student of this institution has caused surprise and numerous speculations. The Communication does not provide details of the suspect's motives or his relationship with the university.
Meaning Case
The detention of Matthew W. falls within the broader context of anti-terrorism in Poland. The ABW regularly monitors the threats associated with extremism, including Islamic radicalisation. Cases such as this emphasize the need for vigilance in the face of potential threats, especially during the Christmas season when the fairs attract crowds of people.
No further details have been released on the planned assassination, but the investigation is ongoing. Authorities call for suspicious behaviour to be reported, which can help prevent similar incidents in the future. The case will be monitored, and possible new information may shed more light on the motives and preparation of the detainee.
