No action is likely to be taken against the security personnel who used pellet guns during the recent protest near Jantar Mantar, as they reportedly followed the prescribed Standard Operating Procedure (SOP), sources said. Before resorting to pellet guns, security personnel reportedly issued warnings through announcements and attempted to control the crowd using lathi-charge and tear gas shells. However, the protesters allegedly refused to disperse and tried to move towards Parliament, following which pellet guns were used. Pellet Guns Used After Other Crowd-Control MeasuresSources said the use of pellet guns came only after other crowd-control measures had been attempted. The final decision to deploy pellet guns was allegedly taken on the orders of a DCP-rank Delhi Police officer.
