Former chess champion Garry Kasparov was arrested after leading a protest to Moscow’s federal election authority offices.
Kasparov was sentenced Saturday to five days in jail for holding an unauthorized march. He had been on his way to give election officials a letter claiming that the upcoming Russian elections are biased toward President Vladimir Putin.
Kasparov is the presidential candidate for the opposition Other Russia coalition. He was arrested at a demonstration in April, when he was levied a fine but no jail time.
On Sunday, Kremlin riot police broke up an anti-Putin rally near the State Hermitage Museum in St. Petersburg.
