An arrest warrant has been issued for an Interunity Management-controlled ship in a charter dispute with Chembulk Tankers.

Connecticut company Chembulk filed a $2m lawsuit last week in a federal court in Baton Rouge, Louisiana, looking to arrest the 26,198-dwt Chem Ranger (built 2010). In addition to targeting the ship, the lawsuit focuses on registered owner Lantern Maritime as the defendant.
