Police have charged Ruslan Sokolovsky, the video blogger who filmed himself playing Pokemon Go inside a Yekaterinburg cathedral, with committing extremism and offending religious sensitivities. Sokolovsky has been detained and awaits trial on Sept. 3 to determine if he will be arrested, his lawyer says. If convicted, Sokolovsky could face several years in prison.

On Aug. 11, Sokolovsky published a video on his YouTube channel showing him entering the Church of All Saints in Yekaterinburg and playing Pokemon Go on his iPhone throughout the cathedral. In a short speech at the beginning of the video, Sokolovsky says he rejects warnings reported in the media that playing Pokemon Go in churches could result in a prison sentence.

“This is complete nonsense,” Sokolovsky said, standing outside the Church of All Saints. “Who could get offended if you’re just walking around with your smart phone in a church?”
