CHICAGO (STMW) – Chicago Police are warning elderly North Side residents of a scam where conmen pose as city workers to enter a home then rob them.

The conmen tell their elderly targets they work for the water department and need to check the water inside the residence then take items that can be carried, particularly jewelry and money, according to an alert from Belmont Area detectives.

Most of the robberies happen between noon and 6 p.m., police said.

The descriptions of the conmen vary, but there are two to three white or Hispanic men between 30 and 45 years old, police said. The heights and weights vary from 5-feet-7 to 6-feet with a medium to heavy build.

Police say residents should secure windows and doors, pay special attention to people loitering in the area and report suspicious people or activity to police.
