Overnight Thursday, Ukrainian border guards, together with the national police, detained a citizen who was crossing in from Russia-occupied Crimea.
In 2014, the 26-year-old man took active part in hostilities, fighting alongside Russian proxy forces in Donbas against the Armed Forces of Ukraine, spokesperson for the State Border Guard Service Oleh Slobodyan wrote on Facebook.
He was part of the so-called "Zorya" battalion and had a nom de guerre"Kosa", law enfoircers learned.
The man was wounded in action.
Earlier, he had been recruited on the territory of Russia, where he was lured under the pretext of getting an easy job.
"This is the usual scheme of involving people into illegal militia by Russia's intelligence services," the report says.
"There is a growing trend of Russia sending from temporarily occupied territories to peaceful parts of the country Ukrainian nationals recruited by Russian special services," the spokesman says.
In 2019, fifty-nine such persons were revealed.
