Sweden boards suspected 'shadow fleet' tanker in Baltic Sea, detains Russian captain

Swedish Coast Guard forces boarded a suspected "shadow fleet" oil tanker in the Baltic Sea near the southern port city of Trelleborg on Thursday, detaining the vessel's Russian captain on suspicion of multiple maritime violations. The operation targeted the Sea Owl 1, a 228-meter tanker sailing under the Comoros flag that authorities suspect was operating under a false flag while appearing on the EU sanctions list, according to Swedish news broadcaster SVT.

Coordinated law enforcement operation

The Swedish Coast Guard conducted the boarding operation Thursday evening outside Trelleborg with assistance from police and the national task force, including a police helicopter. Senior prosecutor Adrien Combier-Hogg confirmed that the ship's commander, a Russian national, is suspected of several crimes. "The suspect is the commander on board the ship Sea Owl 1 and a Russian citizen," Combier-Hogg stated, adding that the investigation concerns suspicions of using false documents and additional violations of maritime law.

Intensive investigation underway

Authorities are conducting what Combier-Hogg described as an "intensive investigation," including searches on board the vessel, interrogations, and examinations of suspected forged documents. Swedish Coast Guard press officer Mattias Lindholm noted the tanker had been heading toward Russia at the time of interdiction. Daniel Stenling, deputy chief of operations at the Coast Guard, expressed serious concerns about the vessel's condition, stating "Our overall assessment is that the risk of safety deficiencies on board is high."

Second interdiction in two weeks

Thursday's operation marks the second time in just over a week that Swedish authorities have taken control of a suspected shadow fleet tanker outside Trelleborg. On March 6, authorities boarded another vessel, the Caffa, whose captain faces similar suspicions of maritime regulation violations and use of false documents. The Caffa has since been placed under an international usage ban by the Swedish Transport Agency. The repeated interceptions highlight Sweden's intensified efforts to enforce EU sanctions and maritime regulations against vessels attempting to circumvent restrictions through deceptive practices.
