EBay Inc. (EBAY) said it’s cooperating with a U.S. Justice Department investigation of its dispute with Craigslist Inc.

Prosecutors are investigating whether EBay employees stole confidential information from Craigslist, according to a copy of a grand jury subpoena. The online classified company claims in a lawsuit in state court in San Francisco that EBay stole the information to start a competing online ad site when the two companies were negotiating over EBay buying a stake in Craigslist.
