The captain of the Adrian Darya 1 is reported to have been offered cash inducements to sail the VLCC to a country that would impound the vessel on behalf of the US.

Akhilesh Kumar is said to have received the offer in an e-mail from Brian Hook, the US Representative for Iran, according to the Financial Times (FT).

The UK business newspaper said the offer was made just four days before the US imposed sanctions on the Iranian tanker and its captain.
