Russian police detained at least 380 activists across the country today for holding unauthorised protests against President Vladimir Putin. A monitoring group OVD-Info said that demonstrations took place after radical opposition politician Vyacheslav Maltsev appealed on his website for supporters to hold protests across the country to end Putin's tyranny. <br/><br/>Moscow police said previously they had detained 263 people for breaches of public order. State news agency TASS reported that many of those detained were carrying knives, knuckledusters and pistols that can fire rubber bullets. <br/>
