Taking More Leave Without Any Leave Balance

It is any real HR story.
one of our employee is taking more leave without having any leave balance in account. And the reporting authority too not objecting the same. When we calculate the total leave availed informations the employee would have already cross the entire balance for the year.
What kind of action to be taken in this case?

Hi Arun,
You should talk to him personally and inquire the reason of his taking leaves.
Then you should warm him that there is no leave left in his account, from now if he takes leave, salry would be deducted and inform as now your leave balance is going negative and you have crossed the entire balance, so we need to deduct you pay for the extra leaves taken.
Moreover, you should have warned him earlier, so now it would have been easier to take such hard action.

Thanks Ms.Priyanka,
I can warn that employee but he was not belongs to my department. And he is reporting to one of my colleque. He / She would really know about this situation. Even after this the same thing is happening.

Pls check ur leave policy and act accordingly. If he/she doesn't have leave balance then deduct the days which taken frm his/her salary.. Before taking any action pls convy this message 2 his line manager and consider his/her advice too.
Thanks
