Story highlights Navalny sentenced to 30 days of detention

Nearly 1,400 people arrested, monitoring group says

Moscow (CNN) Russian opposition leader Alexey Navalny was found guilty late Monday of calling repeatedly for unlawful protests and sentenced to 30 days of detention.

His sentencing followed a day of nationwide anti-corruption demonstrations, during which nearly 1,400 people were arrested amid scuffles with police and reports of tear gas being used.

Navalny, in court in Moscow, accused the judge of helping the police write the justification for his arrest and showed defiance by praising the protesters as "brave, wonderful people."

"I am very pleased that people came out, I am proud that I am a part of this movement in which brave, wonderful people, are not afraid to go out on the streets. Even under the threat of some detentions and so on," he said.

Alexey Navalny speaks after his Monday hearing.

After his sentencing, Navalny tweeted, "30 days. Not only they robbed the whole country, but I'll miss Depeche Mode concert in Moscow because of them."
