Pavlo Hryb's father, Ihor Hryb, earlier told UNIAN his son, 19, had been detained by FSB operatives in the Belarusian city of Gomel where he had arrived by charter bus on Ukraine's Independence Day, August 24, to meet with a girl whom he supposedly met on the internet. It was established he had crossed the Ukrainian-Belarusian border unhindered. The contact with the young man has been lost since then. His father believes that his son was snatched by the FSB over his patriotic views, vocally expressed on social media.
