Moscow massacre, former Russian agent: chip in attackers' brains. The former head of the Russian Interpol office, retired police major general Vladimir Ovchinsky, declared on federal television that chips may have been implanted in the brains of the perpetrators of the terrorist attack on the CR.

"The consciousness of these attackers was disabled: most likely psychotropic substances, neuro-psychological programming and perhaps chips were inserted, because now neurobiology allows control over a person," he said during a broadcast on Russian TV Channel One.
