"They were detained in the course of the investigation of the abduction and robbery of two inhabitants of Kargalinovskaya Cossack village in the Shelkovskaya district," the Interior Ministry officials said.
According to the investigation's information, on Sunday night four unknown people stopped a Zhiguli car, in which there were two inhabitants of Kargalinovskaya Cossack village, on a highway.
The men were pushed into a car and beaten. Their personal things were taken away, their hands were tied, and then the men were thrown onto the roadside.
"Due to the Interception plan which was put into operation, some time later the car with the suspects was stopped at the checkpoint in Shelkovskaya Cossack village," the Interior Ministry officials said.
The suspects proved to be policemen of Chechnya's patrolling and sentry-duty service. Three submachine-guns, grenades, an improvised explosive device, rounds for a grenade launcher, and many cartridges, as well as handcuffs, Scotch tape and black masks were found in their car.
The suspects' complicity in other crimes of this kind is currently being checked.
