Police have detained a suspect in the slaying of Ingushetia's security council head last month, Chechen leader Ramzan Kadyrov said.
"Today, Chechen police officers conducted a successful operation to locate and detain a dangerous criminal. Artur Dolsayev, who was involved in the murder of Security Council Secretary Akhmed Kotiyev, has been arrested," Kadyrov said on his Instagram account Tuesday.
Kotiyev, who worked with former rebels to help them to re-assimilate into the community, was ambushed in his car near the Ingush village of Nizhniye Achaluki on Aug. 27.
His driver, who was his cousin, also died at the scene.
Dolsayev has told investigators that the slaying was organized by an armed group under the leadership of Artur Getagazhev, who in turn reports to the Chechen insurgency leader Doku Umarov, Kadyrov said.
It was unclear what charges, if any, have been filed against Dolsayev.
Umarov leads a group called the Caucasus Emirate that has claimed responsibility for a number of attacks, including a suicide bombing at Moscow's Domodedovo Airport in 2011 that killed 37 people.
Getagazhev's group is suspected of organizing a terror attack in the Ingush town of Malgobek last year and of a number of attempts to kill security officials.
