Three persons, including a branch manager working with a nationalised bank, have been arrested by the Bengaluru Police for defrauding the bank of Rs 1 crore.

Branch Manager Arun fell in a 'money doubling trap' laid by two racketeers Imtiyaz and Basavaraj, who persuaded him to withdraw Rs 1 crore original currency notes from the bank and said they could be replaced with fake currency notes.
