Russian police have stormed into the home of nationalist leader Vyacheslav Maltsev and taken him to Moscow for questioning.

Maltsev, a popular video blogger who unsuccessfully ran for parliament last year, streamed the scene live Thursday from his apartment in the central Russian city of Saratov as police knocked down his door. Accompanied by riot police, an unidentified Russian investigator was filmed ordering Maltsev to get dressed and leave to Moscow for questioning.

Maltsev, whose daily video blogs typically get around 100,000 views, is one of Russia's most popular nationalist figures.

The RIA Novosti news agency later Thursday quoted a Moscow court spokeswoman saying that Maltsev was being questioned in connection with an investigation into an attack on a policeman at an opposition rally in Moscow last month.
