A Vietnamese tanker captain has been jailed for five and a half years for his part in a plot to steal $150m of fuel from a Shell refinery in Singapore.

Doan Xuan Than became the second person to be sentence in a sweeping case that has seen eleven former Shell employees and several others have been charged.

The scam took place at Shell Eastern Petroleum’s Pulau Bukom refinery in 2016 and 2017.
