I am a newcommer to Switzerland. I have a 1-day trip to Lausaane this Saturday (Feb. 5) and I lost may hanycam near the Ouchy station; really terrible

! I checked with the information center (near the lake) but there was nothing there, and the police office was closed at that time. I had to leave lausaane the same night and could not wait there to follow the issue.
Could anybody help me how I can check if somebody have found it? I mean is there any lost and found center in lausaane (in police, station, ...)? any address, email, etc. of them?
Many thanks for your help
