At the Swiss level, there is a procedure to find out what data about you is in the various Swiss police databases. However, where the disclosure of such data is likely to jeopardize an ongoing investigation or would be contrary to overriding public interests, the competent authority may deny you access.
At the international level, the same procedure exists to get Interpol to reveal your data, in particular international arrest warrants (red notice). Interpol will then ask the state that issued the international arrest warrant for permission to release your data.
In both cases, it will be necessary for you to provide a copy of a valid identity card or passport. For confidentiality reasons (country of residence, place of domicile, address), it may be preferable to use a lawyer who must then legitimize himself by means of an original power of attorney.
