It is being reported (here and here) that the European Public Prosecutor’s Office has conducted a raid on the premises of Bulgartransgaz in Bulgaria.
The investigation is said to concern whether natural gas supplied via the Turkish company Botas may include gas of Russian origin and be being done in circumvention of the EU’s Russian sanctions.
This would be the first public and specific investigation by the European Public Prosecutor’s Office into allegation of sanctions breaches.
