This sucks for sure, so sad. I know a lot of stories of thieves, pickpocket etc, even once, me and my GF going to the subway to go to the airport in that arc of triumph square past midnight this guys almost try to rob us, but coming from south america and dealing with all that kind of stuff almost everyday in some unsafe places we are very aware of what going and from far we saw the intentions, body language, IDK but we knew it, and they look like amateurs to us compared with stuff we been witness since we were born and confront them and basically we let them know we knew and if they donn´t show a knive, gun or similar we won´t give them anything and to be honest I think they got scared. We were lucky that time, but my point is that when people come from the safest places on earth like Denmark, Sweden (in the case of Tor, don´t know the other guy) they´re not aware that this stuff can happen, you get robbed, stabbed in MACBA etc. There is a plenty of sketchy people and places out there, you must be careful everytime.
That being said that shitty stuff can happen in public spaces, being robbed from your own hotel room is something planned by employees or an insider, that is not normal even in shitty places and my guess is that red bull have some budget and they weren´t staying in the most shitty hostel ever.
Be safe out there.
