Arrest Following Seizure of Russian Oil Tanker
National Crime Agency (NCA) officers have detained an Indian national on suspicion of sanctions offences after the dramatic seizure of a Russian oil tanker in the English Channel on Sunday.
The individual was taken into custody for questioning by investigators following an operation conducted by Royal Marine Commandos in collaboration with the NCA.
The NCA reported that 24 Georgian and Indian crew members remain aboard the Smyrtos, which is anchored off the Dorset coast.
Details of the Operation
The operation on Sunday involved commandos fast-roping from a helicopter onto the tanker, marking the first such mission carried out by UK armed forces.
Russia operates hundreds of oil tankers that have been sanctioned by the UK and other Western countries in response to its invasion of Ukraine.
British sanctions prohibit vessels from this so-called "shadow fleet" from entering UK ports. Additionally, British firms and individuals are banned from providing financial, insurance, or brokerage services to ships involved in supplying or delivering Russian oil.
The Ministry of Defence (MoD) states that the UK has sanctioned more than 500 such vessels.
Government Statements
Prime Minister Sir Keir Starmer announced in March that British armed forces were "now able to board sanctioned vessels that are passing through our waters." On Sunday, he said:
"This successful operation delivers yet another blow to Russia and reminds those fuelling [Russian President Vladimir] Putin's war in Ukraine that we will not let them hide."
Ukrainian President Volodymyr Zelensky expressed gratitude to the UK for taking an "important step against Russia's oil fleet."
There was no immediate response from Moscow, which has previously described similar interceptions as illegal and "bordering on international piracy."
Vessel Information and Legal Context
According to the tracking website MarineTraffic, the Smyrtos sails under a Cameroon flag.
The vessel commenced its journey on 5 June from Russia's Ust-Luga port, an oil terminal near St Petersburg, before crossing west into the Channel on Saturday, as verified by BBC Verify.
The tanker was sanctioned in July 2025 and has since changed its name from Myrtos to Smyrtos, as well as altering the flag it sails under twice.
The MoD confirmed that the operation took place in international waters, more than 12 nautical miles from the UK coast, and was conducted in full compliance with domestic and international law.
An MoD spokesman stated that the interception was the result of weeks of military and political planning.
International Cooperation
The operation was carried out in close coordination with French authorities, the MoD said, building on recent UK support to its allies.
French President Emmanuel Macron announced on 1 June that French military forces had intercepted a sanctioned oil tanker suspected to be part of the "shadow fleet," with UK assistance.
The MoD informed the BBC that a British helicopter provided support during that operation.
