Journalist Pavel Nikulin from Moloko Plus and photographer Artem Drachev were arrested in Moscow. They were detained while reporting on the demonstration in Manezhnaya Square. Both were arrested despite having proof of their editorial assignment and journalistic identification.
UPDATE: on 19 April, both Nikulin and Drachev were fined 10,000 rubles by a court in Moscow for allegedly taking part in an unauthorized protest, despite being present as journalists.
