27. As regards the purported letter given by the respondent no. 4, the same merely indicates that the respondent no. 4 was ‘returning’ an amount of Rs. 8,500/- to the bank, which was cash which he got from the bank. The said document, by itself, is not proof enough of the attending circumstances for such return and cannot be co-related directly with the incident dated February 23, 2008. Although the said letter says that Vikash (respondent no.4) was mentally disturbed and could not understand “the right situation”, such a blanket statement cannot lead to the conclusion which the petitioner offers by way of explanation. The petitioner failed to report the matter to anyone in the bank, let alone his superior officers, not only on the date of occurrence, but thereafter, before he was prodded to do so by the authorities. Moreover, the petitioner showed no inclination at any point of time to justify the patent discrepancy in the bank’s transactions for the day, before being called upon to do so.
