Green Bay Police have received 13 cases of victims since 2011 of scammers posing as utility workers attempting to gain entry in homes.
Police say the typical scenario involves two men claiming to work together to do inspections. One man distracts the home owner while another attempts to steal items and information from the house.
Officers believe they tend to target the elderly.
They usually drive a van, and police are attempting to locate potential suspects with a truck similar to this one.
If you have any information you're asked to contact the Green Bay Police Department at (920) 448-3208.
