The initial reason(s) invoked by German federal prosecutors in opening an investigation into the Nord Stream sabotage were that

Federal prosecutors are investigating "persons unknown" suspected of "anti-constitutional sabotage" on the pipelines as well as "deliberately causing an explosion." [...]

Germany's federal prosecutor's office usually only opens probes into cases that concern national security, such as terror attacks.

The office said its involvement in the pipeline leaks was justified in that a "violent attack on the energy supply could impact the external and internal security" of Germany, a spokesperson told news agency AFP.

So the [rationale for the] German probe does not actually depend on whether the attack was carried out from German soil (but it turned out that that probably happened as well.)

Clearly the Swedish interest was not as broad/deep, given their stated reasons for dropping/ending their prosecutor's investigation:

the primary purpose of the investigation has been to establish whether Swedish citizens were involved in the act and whether Swedish territory was used to carry out the act [...]

The Danish probe appears to be conducted by police and intelligence services, rather than a prosecutor, but I could be mistaken. Anyway, have the relevant Danish authorities (that are conducting their investigation[s]) said what is the scope of the Danish investigation? (I.e. is it more limited like Sweden's, relating to means or persons, or do they broadly charge that Danish interests are at stake, like Germany did. [Yes, I'm aware the pipelines end in Germany, not Denmark.])

  • The most dangerous thing in any investigation is a possibility of the prove self guilt involvement. So, better to stop it promptly. But that is a precedent of industrial terrorism "legality" Feb 28 at 18:36

A week later we know. It was apparently similar in scope to Sweden's, and is now closed:

"Based on the investigation, the authorities can conclude that the sabotage of the pipelines was intentional," Copenhagen police said in a statement.

"At the same time, it is also assessed that there is not the necessary basis for pursuing a criminal case in Denmark," it said.

[...] Copenhagen police said that the investigation -- which had been carried out together with Denmark's intelligence service PET -- had been "complicated and extensive."

It added that it was not in a position to "provide further comments" in the case.

[...] The decision to close the Danish investigation was immediately criticised by Russia.
