Russian police said on Wednesday they had detained over 400 people, including opposition politician Alexei Navalny, at a protest in Moscow calling for punishment for police officers involved in the alleged framing of journalist Ivan Golunov.

But his supporters went ahead with a protest on Wednesday, a public holiday in Russia, despite being warned by the authorities that their demonstration would be illegal.

Police abruptly dropped drugs charges a day earlier against journalist Ivan Golunov, a rare reversal by the authorities in the face of anger from his supporters who said he was framed for his reporting.
