GREENVILLE, N.C. (WNCN) – Attorney General Roy Cooper was in Greenville Saturday to survey the flood damage and warn people about potential scams.

Cooper said his office has already received more than 150 complaints since Hurricane Matthew hit. He also confirmed two subpoenas have already been served to a gas station and hotel in North Carolina for alleged price gouging.

Cooper warned everyone in the state to be wary of scammers.

“They come in to take advantage of people at a time when they are vulnerable and sometimes desperate,” he said.

Cooper said residents should be skeptical of people who knock on doors to offer repair services following a storm. Instead, he advised people to contact their insurance agency, and contact a reputable business for repairs.

He also asked people to report any abnormally high prices for hotels, food and gas they may see.

“What we need to do is investigate those. We have already served subpoenas on some businesses,” Cooper said.

Cooper also recommended only donating to charities that you know about.

Mayor Allen Thomas said the city of Greenville is on high alert now for possible price gouging.

“We’re waiting for you. If you show up here, we’re going to give you a greeting that you’re not going to want to have. We’re going to look out for our community,” Thomas said.
