Purport behind word ‘uses’
What is essential to satisfy the word “uses” for the purposes of section 397, I.P.C. is the robbery being committed by an offender who was armed with a deadly weapon which was within the vision of the victim so as to be capable of creating a terror in the mind of victim and not that it should be further shown to have been actually used for cutting, stabbing, shooting, as the case may be; Ashfaq v. State (Government of NCT of Delhi), AIR 2004 SC 1253.
