May 28 (Reuters) - Bank of Nova Scotia on Tuesday reported a fall in second-quarter profit as the lender set aside larger loan loss reserves in case customers fall behind on paying back debt in an uncertain economy.

Profit declined to C$2.09 billion ($1.53 billion), or C$1.57 per diluted share, for the three months ended April 30, from C$2.15 billion, or C$1.68 per diluted share, a year earlier.
