SOCHI, Russia -- An activist who shed the light on the environmental impact of Olympic construction in Sochi was ordered Wednesday to serve three years in prison for spray-painting a fence.

A court in the regional capital of Krasnodar converted the suspended sentence given to Yevgeny Vitishko in 2012 into a prison term, according to his lawyer, Alexander Popkov.

"We expected it and so did Zhenya (Vitishko)," Popkov told The Associated Press, adding that the ruling confirms suspicions that Vitishko is "persecuted for his activities."

Vitishko and another activist, Suren Gazaryan, were found guilty in 2012 of "deliberate destruction of property" for spray-painting the fence of what they said was a local governor's property in a national forest where construction is forbidden. Both received a suspended sentence, but Gazaryan was later threated with additional charges and promptly left the country. He received political asylum in Estonia last year.

As a condition for his suspended sentence, Vitishko had to check in regularly with penitentiary officials and inform them of his travel plans. Officials last year petitioned the court to convert Vitishko's suspended sentence into a prison term, claiming that he had failed to inform him of his trip out of town.

Human Rights Watch on Wednesday condemned the ruling, saying that "the case against Vitishko has been politically motivated from the start." The rights group called on the International Olympic Committee to urge Russian authorities to free the activist.
