Several Indiana gas stations are being investigated for gas gouging.
Last week, several stations raised their prices, blaming the threat of hurricane Ike on the gas hike.
In Sullivan, pump prices increased to $4.89 a gallon.
But just a few miles away in Terre Haute, prices were $.80 cheaper.
Michiana also had prices in the 4-dollar range.
Several customers complained, and now, the state Attorney General’s office is looking into the matter.
