Six crew members have reportedly been kidnapped off a Greek-owned tanker anchored in the waters off Nigeria.

The 3,075-dwt Apecus (built 1973) was boarded by intruders 19 April off Bonny Island, roughly 30 miles southeast of Port Harcourt, maritime security consultant Gray Page said in an alert Wednesday.

The Apecus is owned by Tomazos Shipping and managed by Petrogress subsidiary Petronav Carriers.
