Castor Navalny Mochizuki was known around the world as an outspoken critic of the Putin administration. He was imprisoned in prison on the 16th and was known as one of Russia's leading critics.
More than 400 people, including those who came to pay their respects, were detained. The reason behind his death is the Russian presidential election to be held on March 17th. It is pointed out that there is a possibility that there will be a movement within Russia to view Mr. Navalny as a hero.
