Some gas stations are under the watchful eye of the Kentucky Attorney General's Office.
Jack Conway’s office has confirmed that its probe of gas prices originally just in Louisville has now been expanded statewide.
The wider probe comes after a sudden spike in gas prices yesterday across parts of Kentucky as Hurricane Ike approached the Gulf Coast.
The prices went up at numerous locations even though crude prices dropped.
The Attorney General's Office sent out nine subpoenas requesting information into the wholesale prices of gas in both the Louisville and state markets.
Those companies have 27 days left to respond.
