The Ukrainian suspected of coordinating attacks on the Nord Stream pipelines had served in Ukraine’s Secret Service and in the Ukrainian Army’s special forces, Sky News understand. 

Serhii K., 49, was arrested in northern Italy on Thursday following the issuance of a European arrest warrant by German prosecutors.

It is not known whether he was still serving at the time of the pipeline attack in 2022 and Ukraine’s government has always denied any involvement in the explosions.

According to sources close to the case, the suspect has been found in a three-star bungalow hotel named La Pescaccia in San Clemente, in the province of Rimini.

Man arrested over Nord Stream attacks

When military officers from Italy’s Carabinieri investigative and operational units raided his bedroom, he didn’t try to resist the arrest.

The hotel’s employees have been questioned, but no further evidence or any weapons were found, the sources added.

Serhii arrived on Italy’s Adriatic coast earlier this week, and the purpose of his trip was a holiday. He was found with his two children and his wife.

At least one of the four people within his family had a travel ticket issued in Poland. He crossed the Italian border with his car with a Ukrainian license plate last Tuesday.

He was travelling with his passport, and he used his real identity to check into the hotel, triggering an emergency alert on a police server, we have been told.

After the arrest, he was taken to the Rimini police station before being moved to a prison in Bologna, the regional capital, on Friday.

Deputy Bologna Prosecutor Licia Scagliarini has granted the German judicial authorities’ requests for Serhii’s surrender, but Sky News understands the man told the appeal court that he doesn’t consent to being handed over to Germany.

He also denied the charges and said he was in Ukraine during the Nord Stream sabotage. He added that he is currently in Italy for family reasons.

While leaving the court, he was seen making a typical Ukrainian nationalist ‘trident’ gesture to the reporters.

The next hearing is scheduled for 3 September, when the Bologna appeal court is set to decide whether Serhii will be extradited to Germany or not. He will remain in jail until then.

In Germany, he will face charges of collusion to cause an explosion, anti-constitutional sabotage and the destruction of structures.

German prosecutors believe he was part of a group of people who planted devices on the pipelines near the Danish island of Bornholm in September 2022.

Serhii and his accomplices are believed to have set off from Rostock on Germany’s north-eastern coast in a sailing yacht to carry out the attack.

The explosions severely damaged three pipelines transporting gas from Russia to Europe. It represented a significant escalation in the Ukraine conflict and worsening of the continent’s energy supply crisis.

According to a US intelligence report leaked in 2023, a pro-Ukraine group was behind the attack. Yet, no group has ever claimed responsibility.

Sky News understands Genoa’s Prosecutor’s Office in northern Italy has requested their colleagues in Bologna to share the information related to Serhii.

Anti-terrorism prosecutors are investigating another alleged sabotage linked to the Russian shadow fleet oil tanker Seajewel, which sank off the port of Savona last February.

On Thursday, they asked an investigative police unit to figure out whether there is a link between that episode and the Nord Stream attacks.
