For this you have to check whether loan taken amount plus existing loan exceeded aggregate of paid up share capital and free reserve or not?

Secondly at the time of taking loan bank must have asked the board resolution? that resolution is required to filed in mgt14 under 117(3)(g)

this is loan from bank i guess not loan from director as you have mentioned took loan on behalf of the company.

And if the loan took loan in his personal name then lended the same to the company then its prohibited.
