I think as said previously you have been pranked.

yeah you told us via vB, but he could post his mail too
but you told us he left you his mail...

I dont know about what is your forum, maybe he really is but again there is no need to panic
just go in local police and ask to call him there and talk with him live :) not on phone, not searching on google

Thanks for your suggestions guys :)
I shall contact the police tomorrow, just to make sure

np, yeah, that will be the smartest thing to do, let them do the rest
not only to ask them does he exist, but to contact him
