Three more gas stations in North Carolina must turn over information as part of Attorney General Roy Cooper’s ongoing investigation into possible price gouging at the pump, according to a press release.

“Consumers deserve to be treated fairly when they fill up,” Cooper said in a written statement.  “If we uncover evidence that Hurricane Ike was used illegally to run up prices and gouge consumers, we’ll take legal action.”

Subpoenas were issued to a gas station in Charlotte and two gas stations in Yadkinville. According to a press release, the gas stations were allegedly selling gas between $4.49 and $5.35 per gallon.

The station owners have 10 days to provide documentation to the Attorney General’s Office including information on their costs.

Last week, Cooper’s office sent subpoenas to owners of 23 gas stations who reportedly sold gas for more than $5.35. 

According to Cooper’s office, nearly 4,300 people have reported gas price gouging since Sept. 12, 2008. 

Consumers can report suspected price gouging to the Attorney General’s Office by visiting www.ncdoj.gov to fill out a price gouging complaint form or by calling 1-877-5-NO-SCAM toll-free within North Carolina.
