Strange to say the least.

Where does he work ?
What does he look like ?

So we can hire our local spying crew...

Did you try sending him an email at least to alert him ?

Call his company and ask for him (Assuming you already know where he'd be working)

We can provide you at least with the number of the company. If you don't have it you can search in Google for it. (Make sure you search for "COMPANYNAME 974")

Good luck.
