Not that I am aware of, although if a convention does call the police one of the first things to do (after making sure that the complainant is being taken care of appropriately) would be to let the venue know. In fact, my inclination if at all possible and if it wasn't likely to induce delay would be to go to the duty manager and say "there has been an incident that requires police attention, please call them now." That way, the venue is in the loop from the outset.

(I appreciate that to do this requires that the convention has staff confident about doing this, and a relationship with the hotel that means that such a request will be honoured immediately. This is thus the sort of contingency that ought to be discussed with a venue in advance, .)
