Interest collected by bank Rs 14000 comes in Debit side or credit side in double entry cash book

Dear student interest collected by bank means that the interest charges are debited from our account as Bank charges. is interest collected by bank are in the nature of charges then the same will be credited in the double column cash book. But if interest collected by bank are not in the nature of charges but as an income of ours has been credited in the bank directly then the same will be entered on the debit side of cash book. Regards
