Japanese manager Mizuho Sangyo says reports of crew being involved in drug smuggling in Turkey are incorrect.

Police and coast guards found 25 kg of the drug in a box attached to the hull of the 177,000-dwt Frontier Falcon (built 2011) in Canakkale on Saturday.

Police detained seven people, including the master and chief officer, after the vessel arrived from Colombia, Hurriyet Daily News reported.
