Unless there is an extradition treaty between Qatar and Pakistan, only then he can be taken back to Qatar to be arraigned, as no government will be willing to hand over its citizen to a foreign country without such treaty.

All GCC countries are linked to each other, so if you plan on coming back to ANY GCC member country, think twice. Moreover, after you have paid it in full from your country, request a letter of no obligation from the bank, otherwise you have no proof that the payment had been completed.

Goodluck!
