Polish Interior Minister Marcin Kierwiński announced the detention on X hours after security officials convened an emergency session at the counterterrorism centre involving police, the state protection service and the internal security agency. Kierwiński wrote that the man who threatened and planned an attack on Prime Minister Donald Tusk has been detained by Polish police. Prime Minister Tusk posted separately on the platform to thank officers for their swift and decisive action while a government spokesperson described the matter as one authorities were treating with the utmost seriousness.
Interior Ministry spokesperson Karolina Galecka said an email containing information about the potential attack had been forwarded to police by the State Protection Service responsible for ministers’ security, according to a briefing covered by Reuters. Jacek Dobrzyński, spokesperson for the minister overseeing intelligence services, told reporters after the meeting that authorities assessed a high probability the threats would be carried out and were treating the situation extremely seriously. A source within the intelligence services indicated the tip included addresses linked to both Tusk and Kosiniak-Kamysz, Notes From Poland reported.
The development unfolded against a backdrop of deepening political polarisation in Poland coupled with security concerns stemming from the country’s proximity to the war in Ukraine and its strong support for Kyiv, Reuters noted. Tusk had spoken in 2024 of receiving threats in the aftermath of the assassination attempt on Slovak Prime Minister Robert Fico. Officials have reported a rising volume of worrying messages and threats directed at politicians in recent months.
In August 2026 police detained a 23-year-old man accused of calling for the assassination of senior Polish politicians after discovering an online post in a firearms-related group that proposed organising such an attack, the Central Bureau for Combating Cybercrime said in a statement. The suspect from the eastern Lublin region faced charges including publicly inciting crime and preparing acts aimed at genocide or crimes against humanity with a court ordering 30 days of detention and potential penalties of up to 20 years in prison. Additional cases in September included the arrest of a 56-year-old man in Przemyśl and a 52-year-old in Oława for posting online threats against Tusk along with three teenagers linked to neo-Nazi online communities promoting violence, according to Notes From Poland.
The latest incident coincides with heightened national alertness following a series of school stabbings earlier in the week that have compounded public safety concerns, the Associated Press reported. Dobrzyński noted that month after month more such threats reach police yet emphasised that credible intelligence of this nature receives immediate and rigorous response. Tusk’s office confirmed he was informed of the potential danger early on October 11 before the suspect’s arrest was publicly announced.
Poland has experienced several foiled plots in recent months including the August detention of a Russian national accused of planning the assassination of a dual US-Ukrainian citizen in Warsaw on orders from Moscow’s intelligence services, Prime Minister Tusk stated at the time. That operation, carried out with US cooperation, was described by authorities as the first known Russian-directed attempt to kill an American on NATO soil outside the United States. Officials have repeatedly underscored the need for vigilance amid hybrid threats linked to the regional conflict.
