Spanish authorities detained early on Tuesday a yacht called "Lady Anastasia" owned by Russian oligarch Alexander Mikheyev, who is under European Union sanctions, a police source told Reuters.
The yacht cannot leave the marina of Port Adriano in Mallorca, where it is now moored, the police source said.
Spanish authorities are complying with a European Union decision to block assets owned by a list of wealthy Russians with links to President Vladimir Putin.
