The 27-year-old resident of Nazran, the largest city in Ingushetia (a republic neighboring on Chechnya on the west) was detained at the Kavkaz federal check point, the regional headquarters for the North Caucasus anti-terror operation reports.
"Preliminary investigation revealed that the detainee was a member of the terrorist group under the command of Arab mercenary Abu-Dzeit, who was killed in February," the report says.
Abu-Dzet's group perpetrated a number of terror acts against the population of Ingushetia and Chechnya. For instance, "the group took part in the assault on Ingushetia in June 2004, killing over 100 locals, law enforcement and federal forces officers", the HQ said.
Currently, investigators are verifying whether the detainee was involved in that event and other serious crimes against the population of North Caucasian republics of the Russian Federation.
