West African pirates boarded a tanker managed by Evangelos Marinakis-controlled Capital Ship Management on Sunday night, kidnapping four crew members.

Security consultancy Dryad Global said the 38,000-dwt Agisilaos (built 2006) was attacked by an unknown number of gunmen while underway in Ghanaian waters, 75 nautical miles (139 km) south of Lome in Togo.
