One Connecticut utility company is advising customers to make sure employees present identification after people have recently posed as utility workers.
Duncan Goodall told Eyewitness News that a man came to his door asking him to see his United Illuminating bill. However, Goodall did not buy it.
"You don't actually expect me to give some stranger who comes to my door a document about my energy usage," he said.
Police are urging people to be extra careful after they have been hearing about more and more of these encounters.
Those posing to be utility workers could be after information on your bill to steal your identity.
"People should not engage with people who say they are from a utility company ringing their doorbell," said New Haven police Officer Dave Hartman.
UI officials said their residential visits are always set up in advance. Police said to call the utility and look for their vehicle.
"If you look outside and see a utility truck, generally after that they may be some legitimacy," Hartman said.
UI officials sent out an alert to its customers last month about imposters.
In the alert, they told customers if anyone who says they work for UI asks for personal information or acts suspiciously to call 911 right away.
