In July 2026, joint Polish‑Austrian investigations led to the conviction of eight Polish football ultras for a violent robbery on Austria’s A9 highway, with three additional suspects arrested in Poland and awaiting extradition. The case highlighted cross‑border police cooperation and the use of European arrest warrants. By early August 2026, Polish law‑enforcement agencies continued a wave of arrests across the country. CCTV footage helped police detain a graffiti suspect in Kraków, a robbery gang in Warsaw, participants in a street brawl in Kościerzyna, and a perpetrator of an anti‑Ukrainian assault in Kraków. Separately, a Bulgarian national was charged with forcing women into prostitution in Tarnów. These actions illustrate ongoing domestic policing efforts against a range of offenses, from property crimes to xenophobic violence and human‑trafficking, following the earlier high‑profile cross‑border case. Overall, the period shows Polish authorities actively pursuing both international and local criminal activity, employing surveillance tools and international legal mechanisms to secure arrests and prosecutions. ## Timeline ### 2026-08-06: Poland police arrest suspects in graffiti, robbery, brawl and anti‑Ukrainian assault Polish authorities arrested suspects in a Kraków graffiti case, a Warsaw ATM robbery, a Kościerzyna brawl, an anti‑Ukrainian assault in Kraków, and a Tarnów human‑trafficking charge. 11 sources. https://clstr.news/cluster/five-georgian-nationals-detained-in-warsaw-after-robbery-attack ### 2026-07-18: Polish football ultras arrested for robbery on Austria's A9 highway Polish football ultras who attacked two Croatians on Austria's A9 highway have been arrested in Warsaw and Ząbki after joint Polish‑Austrian police work; eight were already sentenced, three await extradition. 3 sources. https://clstr.news/cluster/polish-football-ultras-arrested-for-robbery-on-austrias-a9-highway --- Cite as: Polish police arrests and cross‑border crime.
