The US Department of Justice is carrying out a criminal investigation into the role of several individuals at Enron.
One former Enron executive, Stephen Kopper, has already pleaded guilty and is thought to be spilling the beans about the actions of some of his former colleagues.
Enron executives could be prosecuted for concealing evidence. Other charges being investigated include defrauding Enron’s pension fund.
The FBI, part of the Department of Justice, is charged with investigating federal crimes.
FBI agents in Houston have already been involved in sealing off Enron’s offices after allegations that crucial documents were being shredded
The Justice Department is also in charge of anti-trust investigations brought against companies if they abuse their monopoly position.
The Justice Department had to bring in special prosecutors, though, because nearly all 100 lawyers in its Houston office excused themselves from the case, citing possible conflicts of interest.
