On consideration of submissions made on behalf of the respective parties and the material made available for my perusal as well as the evidence collected during investigation, which has been placed on record by way of copy of the charge-sheet, and more particularly looking to the gravity of the offence, but without expressing any final opinion on the merit and de-merit of the case, I do not find any substantial change in the facts and circumstances of the case so as to allow this application for grant of bail of the petitioner. Mere filing of the chargesheet cannot be said to be substantial change in the facts and circumstances of the case.
