MISSING YOUNG MAN IN LISBON

Hi all, I'm quite desperate and I need your best advice.

My friend's been missing for almost 48 hours.

We are two expats currently in Lisbon, Portugal.

I don't know his last location but I know he was with some friends of his and he was supposed to come by my house shortly and he never did. There's been no contact with any other person I know of and the police has been notified but I need to reach as many people as I can.

Please any advice is welcome at this moment.
