A leaked email has revealed that BP faces criminal investigation into the huge 270,000 gallon oil spill the company caused in Alaska in March. Although  BP received the subpoena in April from a Grand Jury, it has only now become public, with the leaking of an email.

The news wiped three percent of BP’s share price and threatens BP’s carefully crafted image as a “green” oil company. If BP is found guilty, it could lead to senior managers being imprisoned. I wonder if BP CEO, Sir John Browne is having sleepless nights.
