Svyatoslav graduated from flight school in Ukraine, after which he returned to Belarus and completed an internship at Belavia. His father was also a pilot.
He continued to maintain contact with his former classmates. Some of them joined the Ukrainian Armed Forces after the outbreak of full-scale war in Ukraine. It was his correspondence with these people that could have served as grounds for persecution. Shortly before his arrest, the man sent a friend a photograph of the plane on which he had completed his internship, stating that he would be flying it. He was subsequently detained on June 10, 2025.
