MOSCOW - Russian police detained the alleged head of a disbanded Islamist cell that had planned a series of attacks in Moscow, Russia's counterterrorism agency said on Thursday.
Yulay Davlatbayev was arrested in Moscow's Mytishchinsky district by special forces from the Federal Security Service, said the Federal Security Service, which released photographs of his arrest early on Thursday.
Putin has ordered security to be stepped up ahead of the 2014 Winter Olympics in Sochi, which will be held near the North Caucasus mountains where Islamist insurgents wage daily violence to turn the region in to an Islamic state.
Russian officials say Davlatbayev ran a cell of the Islamic Party of Turkestan, a group Russian police say they smashed in a shootout last month.
Officials said the group had been planning attacks in the capital Moscow, including on May 9 when Russia celebrates the defeat of Nazi Germany in World War Two.
