Income of a nri

Dear All ,

One of my NRI friend earned Long term capital gain from sale of mutual fund units. LTCG is Rs.1.5 lakhs. Bank has deducted Rs.46000 towards TDS u/s 195 @ 30.9%. He do not have any other income.

My question is can he claim income tax refund ? If yes , how he can do so? Does he required to appoint somebody as his representative? Pls guide. What other things I should keep in mind while filing his return. Thanks in advance.
