The kettle, stand and sign were taken Saturday afternoon when the two workers manning it outside a Jewel, took a lunch break at the same time, according to the Daily Herald.
Witnesses said they saw four boys take off with the rig, which officials say is very heavy.
The kettle belongs to the Salvation Army Oakbrook Terrace Corps. Its estimated worth is about $750, but it could be more depending how generous passersby were before the kettle was swiped.
Salvation Army officials say there could've been anywhere between $200 and $700 inside the kettle and worry the thieves will run a scam by setting it up and collecting money elsewhere.
