Report the matter to the cantonal police responsible for your place of residence. They will then initiate the
necessary investigations. You can search for police stations in your area and their telephone numbers on
the Suisse ePolice website: https://www.suisse-epolice.ch/#/search-station (in French, German, Italian).
Stop contact with the fraudster completely and block him or her on all channels.
If you are contacted by other supposed "authorities" (e.g. INTERPOL, foreign police authority, a victim's
lawyers, etc.), do not respond.
Discuss the matter with a person you trust and seek psychological help if the issue is very distressing.
If you have financial problems, contact the debt counselling centre in your canton.
