Legally the paki can't be touched since there are no official letters. However, if you're saying HE withdrew the money himself from the ATM, you can go say he stole your card's PIN and took the money without your approval (a bit far-fetched I know, but if this guy's a bastard, this is a last resort). ATM machines have cameras and they can prove he did it. good luck with that and in the future don't trust people with this much money, you never know what might happen.
