Germany has issued a European arrest warrant against a Ukrainian diving instructor, who was allegedly part of the group that blew it up the Nord Stream gas pipelines, according to a report by three German media outlets published today Wednesday.

German investigators believe the man, who was last known to be living in Poland, was one of the divers who in September 2022 planted explosive devices in pipelines running from Russia to Germany through the bottom of the Baltic Sea, Sueddeutsche Zeitung (SZ) and Die Zeit newspapers reported, and German state broadcaster ARD reported, citing unnamed sources.

The attorney general’s office declined to comment on the report.

Germany asked Poland in June to arrest the man in question, according to the report.

The Polish attorney general’s office did not immediately want to comment on the matter.

News magazine Spiegel reports today, citing security sources, that the suspect is believed to have since fled Poland.

Another man and a woman –also Ukrainian diving instructors– have been identified as part of Germany’s investigation into the alleged sabotage, but so far no arrest warrants have been issued for them, according to SZ, Die Zeit and ARD.

It remains a mystery who was behind the explosions that destroyed three of the four gas pipelines, which have been a controversial symbol of Germany’s dependence on Russian gas since Moscow’s forces invaded Ukraine in February 2022.

Russia and the West have accused each other of being behind the blasts. Both have denied involvement and no one has claimed responsibility.

A Swedish investigation found traces of explosives in various items recovered from the site of the explosions, confirming that the explosions were deliberate actions.

In January 2023, Germany raided a ship it said may have been used to transport explosives, and told the United Nations it believed trained divers planted explosive devices in the pipelines. at a depth of about 70 to 80 meters.
