The U.S. Department of Justice will sue Apple as early as tomorrow morning over allegations of fixing eBook prices with five major publishers, according to Reuters. The five publishers, which are also in question, will be looked at later in the week.

The Justice Department is investigating alleged price-fixing by Apple and five major publishers: CBS Corp’s Simon & Schuster Inc, HarperCollins Publishers Inc, Lagardere SCA’s Hachette Book Group, Pearson and Macmillan, a unit of Verlagsgruppe Georg von Holtzbrinck GmbH.

A lawsuit against Apple, one of the parties not in negotiations with the Justice Department for a potential settlement, could come as early as Wednesday but no final decision has been made, the people said.

The news of a lawsuit comes just weeks after the Department of Justice launched a probe into Apple and the five publishers. We will keep you updated with any more news about this case.
