Any successful career criminal knows that when you have stolen millions of dollars, you don’t draw attention to yourself by going on a luxury spending spree. It is the cardinal rule for avoiding detection of your misdeeds.

Juandi bin Pungot, a former Shell Eastern Petroleum employee caught up in Singapore’s fuel oil heist, clearly did not get that message.

Juandi pleaded guilty in the High Court of Singapore on Tuesday to 36 charges stemming from the theft of more than 300,000 tonnes of marine gasoil from Shell’s Pulau Bukom refinery between 2007 and 2013.
