Welcome to CC
As a responsible Host send the Guests a message, if you haven't already, and let them know how concerned you are that such an incident has happened & advise them that this is not a normal thing to happen, if that is the case, in your neighbourhood.
Ask them if they have found somewhere where they are safe & reassure them you will still be available to talk if they want, maybe invite them to your home duting the day, or to meet up somewhere safe to discuss the situation & what they would like to see happen.
I'm sure they will understand as the anti social behavior is not your fault.
Whilst it's an unfortunate incident, focus on what happens inside your home they should prioritise first & foremost.
All the Best
