Die Zeit has to say: "Ermittlungsarbeiten im Block-Prozess hatten den Fall ins Rollen gebracht."[1] = "Investigatory work during the [Christina] Block case had triggered this."

Now who's Christina Block?

"Die 53 Jahre alte Hamburger Unternehmerin Christina Block ist angeklagt, nach einem langen Sorgerechtsstreit eine israelische Sicherheitsfirma damit beauftragt zu haben, ihren damals 10-jährigen Sohn und die damals 13 Jahre alte Tochter vom Wohnort des Vaters Stephan Hensel in Dänemark nach Deutschland zu entführen."[2]

=

"The 53 year old entrepreneur from Hamburg is indicted for, after a long fight over custody, having hired an Israeli security company to abduct her 10-year old son and 13-year old daughter, to bring them to Germany from their father's residence in Denmark."

…

So, that's exactly one very likely guess which [if any] foreign country was involved here. (Hint: it's not Denmark.)

[Ed.: NB: there's no guarantee any foreign country is involved. AIUI misappropriating state secrets is espionage even if you just shove them up your attic.]
