The Downers Grove Police department issued an alert Thursday warning residents of a scam being used to gain home entry and commit theft.
In two incidents, which recently occurred in a neighboring community, residents said a man or men came to their home claiming to be installing underground pipes in the area, police said.
In the first incident, the homeowner was lured in her kitchen by an offender while another man entered home. After the two had left, the homeowner realized that prescription medications and other valuables were missing, police said.
In the second incident, two men approached a home in the same manner, claiming to be underground pipe installers. When the resident unlocked the screen door, the offenders pushed their way into the home, but left when they saw the family's dog. No items were taken.
The offenders are described as male, between the ages of 30 and 40, clean shaved, stocky build and approximately 5-foot-10 in height. They were wearing construction clothing and left the scene in a dark-colored sedan, police said.
Downers Grove police urge residents to be cautious when allowing strangers to enter their home. If someone suspicious is at the door, residents should immediately call 911.
