Ships connected to sanctioned banks continue sailing, even as authorities crack down on Russia's commercial fleet.

Following the arrest of the 8,831-gt Baltic Leader (built 2000) in France over the weekend for its connections to blacklisted PSB, four other PSB-linked ships are still on the high seas of a total of seven it either manages or owns.

All four have Dagestan-based Transmorflot as either technical manager or registered owner, according to shipping databases.
