TALLAHASSEE, FL --- Florida Attorney General Bill McCollum issued subpoenas to four companies Sunday and ordered them to document the purchase price each paid for gasoline sold at their filling stations in the state. 

The attorney general's office said it received more than 350 complaints about gas price gouging over a four-day period beginning Sept. 11.

The subpoenas went to the corporate offices of Flying J, Dodge’s Gas Stores, Valero and Pilot Travel Centers, American City Business Journals reported.

"Price gouging is strictly prohibited in Florida during a declared state of emergency and my investigators have been working throughout the weekend to determine whether Floridians are being taken advantage of," McCollum said. "Passing along a justifiable increase in cost to consumers is legal, but we will not tolerate gouging for greed."

Consumer complaints primarily came from the Tampa area, South and Central Florida and the Panhandle.
