Glen Ellyn Deputy Chief William Holmer said late Friday that investigators are looking into six burglaries with similar characteristics throughout the center of the village.
Glen Ellyn police continue to investigate a "series" of home burglaries that occured between September and November, and want residents to keep an eye out for suspicious people coming to their door.
In a late afternoon news release Friday, police did not indicate how many or where in the village the burglaries have been reported, but said most involved burglars forcing open a door and quickly taking jewelry before fleeing.
"Police are encouraging residents to pay attention to their neighborhoods for situations that do not seem to fit," the release stated, noting burglars appear to be targeting homes were no one is home.
To determine if anyone is home, burglars might "knock on doors with a prepared story about why they are there" if someone answers. If no one responds, the house might be considered a target, police said.
Additional information was not immediately available Friday afternoon.
Police asked that anyone who sees suspicious activity to call 911.
