Poland stated on Friday that it had detained an expert athlete suspected of spying for the Russian authorities, within the 14th arrest stemming from the dismantling of what the authorities say was a Russian spy ring that aimed to sabotage arms shipments to Ukraine.

Polish prosecutors stated in a statement that the suspect, a Russian citizen, was related to a community that “conducted intelligence and propaganda activities against Poland and prepared acts of sabotage” for Russia. They didn’t identify the suspect, although Polish news sources reported that he was an expert hockey participant.

“Russian spies are falling one by one!” stated Poland’s justice minister, Zbigniew Ziobro, in a Twitter post on Friday. “A spy who operated under the guise of a sportsman has been captured.”

Officials stated the suspect was dealing with espionage fees punishable by as much as 10 years in jail.

In March, Polish prosecutors detained 9 foreigners who had been accused of spying for Russia and plotting to sabotage Polish infrastructure used to move Western arms into neighboring Ukraine.

Poland, a NATO member and certainly one of Europe’s staunchest supporters of Ukraine, has been a significant transit level for weapons and ammunition supplied by Western nations to assist Ukraine defend itself in opposition to Russia’s invasion. The presence in Poland of a Russian spy ring making an attempt to break its infrastructure would sign a dangerous escalation by Moscow, which has to this point prevented hanging at targets inside alliance territory.

The Kremlin’s spokesman, Dmitri S. Peskov, on Friday recommended that Moscow’s embassy in Poland would “clear things up.”

“Of course the world of the embassy now is very hard,” he added, “because of the frenzied, Russophobic position.”

Prosecutors stated that the suspect, who arrived in Poland in 2021, was paid to hold out “activities involving, among other, identifying critical infrastructure” in a number of provinces.

Polish news media reported that he performed with the nationwide hockey staff, Zaglebie Sosnowiec.

The staff’s coach, Grzegorz Klich, confirmed that the suspect was arrested earlier this month, however that he had signed to play with the staff earlier than Russia’s invasion of Ukraine in February 2022.

“We did not have any suspicions against him before that,” he was quoted as saying in an interview revealed Friday in Fakt, a Polish tabloid. “He behaved normally. That’s why we are surprised by this case.”

Polish intelligence officers stated they detained the suspect within the province of Silesia, southern Poland, the place he had carried out most of his actions.
