In June 1993, Geliskhanov ordered disarmament of all "illegal armed formations" and banned civilians from bearing arms in public (a right given to the people by Dudayev earlier). He then personally led the breaking up of an opposition rally in central Grozny, during which some 15 people were killed; a year later, he directed large-scale arrests of opposition members. Geliskhanov's DGB successes included the arrest the Chechen mafia boss Nikolay Suleimanov and the capture of two high-ranking officers of the Russian Federal Counterintelligence Service (FSK, at the time the main successor agency to the KGB) clandestinely deployed to Chechnya. Ruslan Labazanov, opposition co-leader, crime kingpin and renegade former head of Dudayev's bodyguards, publicly swore to kill "especially Dudayev and Geliskhanov."
