Sweden says ship seized in Baltic Sea had false flag, one crew member notified of crime

"Our investigation so far strengthens our suspicions and our opinion that this ship has extensive sea safety deficiencies," Andersson said on Saturday.

"We also have information that the vessel would be on the Ukraine sanctions list," he said.

Most of the 11 crew members on Caffa, which according to ship-tracking service MarineTraffic is a 96-metre general cargo ship, were Russian, Andersson said.
