An Alpha Bulkers Shipmanagement capesize is under arrest by a Chinese buyer who believes he was unfairly treated in a scuttled ship sale.

The dispute is a side effect of China's de facto ban on Australian coal imports.

TradeWinds understands that the arrest at the weekend came as an unexpected reversal for Alpha Bulkers after the 170,400-dwt Alpha Era (built 2000) had waited at anchor for six months to be permitted to discharge.
