Warsaw police have arrested a man suspected of stabbing two Ukrainians on a bus over their nationality, police said. A court ordered him held in custody, and the charges he faces carry long prison terms.

Russia's full-scale war drove nearly a million Ukrainians to seek protection in Poland, and attacks on them for their nationality grew this year. Polish police received 180 reports of hate crimes against Ukrainians in the first half of 2026, over 30% more than a year earlier.

Police tracked the suspect to a forest

The attack took place on a Warsaw city bus in mid-October. The attacker stabbed and slashed two passengers, both Ukrainian citizens, and fled before police arrived. Both victims went to hospital with multiple stab and cut wounds. Police found that he attacked them because of their nationality.

Officers quickly identified the suspect but spent days locating him. The 30-year-old was hiding and living in a forest in Warsaw's northern Bielany district, where police detained him last weekend.

He faces three charges. Two concern the bus attack: attempting to cause grievous bodily harm, and causing injuries lasting more than seven days. The third covers threats against another man at a Warsaw venue in August 2024.

Police said he acted as a repeat offender, within five years of serving a prison term for a similar crime. The charges carry three to 20 years in prison. At prosecutors' request, a court ordered him held for three months.

This year's attacks on Ukrainians in Poland

In early August, Ukraine's ambassador to Poland, Vasyl Bodnar, said anti-Ukrainian remarks and attacks had risen by about 30%. Days later, people rallied in 22 Polish cities against violence toward Ukrainians and other minorities.

Other recent cases this year include:

• In late July, police in Wrocław detained two of three men suspected of beating a young Ukrainian couple.
• On 14 August, a woman allegedly attacked a Ukrainian girl and her younger brother in a Bydgoszcz park after hearing them speak Ukrainian. Prosecutors charged her four days later.
• In September, a man punched a 20-year-old Ukrainian tourist in the head at a crossing in central Warsaw, knocking him unconscious. Police detained the attacker, who gave no motive.

Tensions rose again in late September, when a Ukrainian man allegedly killed a priest in a knife attack at a monastery in Jarosław. Bodnar said some Polish politicians and journalists used it to argue for deporting Ukrainians.

Meanwhile, police in southwestern Poland detained a Russian citizen suspected of spying, after catching him photographing trains and railway infrastructure. Russia's suspected sabotage campaign keeps reaching Poland and the rest of Europe, and Ukraine's intelligence warned last week that Russia may stage sabotage in Eastern Europe and try to pin it on Kyiv.
