Newly filed documents show federal agents were looking for more data when they served a second search warrant on Pilot Flying J's data center last Friday.
That facility is located on Weisgarber Road.
The company is being investigated for an alleged scheme that may have reduced rebate checks owed to some trucking companies.
Federal agents say they seized 18 different back-up tapes, and other data including databases and e-mail exchanges.
Meanwhile, attorneys for a Georgia trucking company filed a temporary restraining order Thursday against Jimmy Haslam, to ask a judge to order him to stop contacting potential victims of the alleged rebate scheme.
The documents claim that Haslam is contacting the companies, getting releases from them and settling claims before the companies even know the full extent of their claims.
