Should i file income tax return ?

Yes. Not only to claim TDS, but as per law, prima facie on facts narrated, your friend is liable to file return of income.

Primafacie fact that your friend's income exceeds the gross total income( before Chapter VI deductions)  requires him to file the return. Even if it is not so, to get TDS refund from IT department, you have to file a return.

It is better to file Income tax return in time
