Editor-in-chief of the online newspaper Strana.ua Ihor Huzhva was detained in Kyiv on Thursday evening, Ukrainian Prosecutor General Yuriy Lutsenko has said.

"Huzhva who demanded and received $10,000 for not publishing compromising materials about an incumbent politician has been detained as part of an investigation by the State Fiscal Service and the Kyiv Prosecutor's Office," Lutsenko wrote on Facebook on Thursday evening.

The investigators have footage and photo evidence of this offense, he said.

Huzhva earlier reported about a raid that was under way in the Strana.ua office on Thursday. "A raid is under way in our editorial office on trumped-up charges," he wrote on Facebook.

"The entrance of the business center's is blocked," she wrote on Facebook. According to her, Huzhva was in the office at that moment.

Lawyers arrived later, she added.
