Several boxes had disappeared from the home of Tara Deihm and her neighbors recently.
So the Sinking Spring woman decided to take matters into her own hands and set a so-called "Grinch Trap".
Deihm set up a surveillance camera then filled several packages with trash.
Sure enough, the alleged thief took the bait.
Police say that is Luis Otero-Gonzales walking onto Deihm's porch, looking around, then snatching the fake deliveries.
He was arrested the same day.
Investigators believe Otero-Gonzales may also be responsible for similar thefts.
He's expected to face additional charges soon.
