FBI agents searched two buildings and loaded dozens of boxes into a truck Wednesday as part of what has been called “international” antitrust investigation involving several companies. One is Eagle Global Logistics, based in Houston.

Some of the agents were from the Greater Houston Computer Forensics Laboratory. They’ve been looking at computer hard drives.

The FBI isn’t talking on the record about what it’s looking for and neither is the Justice Department.

But a company spokesman told us government agents raided the office and an affiliate’s offices in London as well as other air and ground transport companies around the world.

He says it’s part of a much larger investigation into antitrust activities involving "surcharges."

Eagle Global spokesman Ray Waters said the company does not believe the investigation "is related to government contracts, nor is it limited to EGL."

He said the agents arrived with a subpoena, and added the company is cooperating fully.

In August 2006, Eagle Global paid a $4 million settlement to the justice department after an executive pled guilty to adding 1 million dollars in fraudulent war surcharges, shipping military goods from Dubai to Iraq.

In June of this year, it paid $300,000 to settle allegations its local agent in Kuwait overcharged the military in shipments to Iraq.

Waters said he has no reason to believe today’s search was connected with those previous investigations.
