The former deputy was arrested in a case of unpaid rents in 2015 and risked up to five years in prison. His supporters saw his arrest as a form of punishment for wanting to run for office.
He was released Thursday evening without any charges being brought against him – a rare turnaround on the part of Russian authorities. His relatives welcomed his release but suggested that he would not be allowed to run for legislative elections this fall.
