Valentin was detained in a criminal case opened after a protest that took place in Pinsk on the night of August 9-10, 2020 against falsifications in the presidential elections. After the detention, the man felt ill and was taken under escort to the Pinsk Central Hospital, where he was diagnosed with a pre-infarction condition and placed in intensive care. As soon as his condition improved, he was transferred to a temporary detention facility and later convicted of participating in "mass riots."
He was released in August 2024 under a pardon.
