Hawaii Gas  is warning its residential customers about a scam involving an individual impersonating a company employee in an attempt to gain access to their property.

The company reported at least one instance in East Honolulu where a customer was approached by an individual wearing blue coveralls who arrived in a white unmarked truck, a Hawaii Gas spokesman said in a news release.

The impersonator claimed to be from a company called Hawaii Star Energy hired by Hawaii Gas. The impersonator then requested access to the property.

Hawaii Star Energy is not an actual company, and Hawaii Gas does not hire third parties to read meters, according to the news release. The spokesman said Hawaii Gas wanted to emphasize to its customers that all company employees wear a Hawaii Gas patch on their coveralls and carry a Hawaii Gas identification badge.

Hawaii Gas encourages its customers to call customer service at 535-5933 if they suspect suspicious activity or have any questions.
