Police detain suspected organizer of twin blasts in Southern Russia
Pakhrutdin Akhmedov was detained after the car in which he was traveling with two other men was stopped for a document inspection.
The men were carrying a pistol, bullets and a grenade.
Akhmedov is alleged to be behind the two suicide attacks that claimed lives of ten people and left 37 injured.
The first blast went off when a suicide bomber blew himself up in a moving car. About 15 minutes later, when investigators arrived on the scene, another suicide bomber dressed as a policeman rushed into the crowd and detonated an explosive vest.
