Joseph Grabenhofer, Pawel Loboz Arrested For 'Returning' Galaxy Tablet Box Full Of Rocks

"A box of rocks" is often the benchmark used to describe dumb ideas; but for two southwest suburban teens, it was the basis of a fraud attempt that got them both arrested.

Joseph Grabenhofer and Pawel Loboz, both 19, are facing misdemeanor retail theft charges after police say the duo purchased a tablet computer valued above $400, filled the box it came in with rocks, and then attempted to return it, according to the Chicago Sun-Times.

Plainclothes Orland Park police officers noticed Grabenhofer and Loboz collecting rocks at a construction site near Orland Square Mall before Grabenhofer purchased a Galaxy tablet at Sears, CBS Chicago reports. Shortly afterwards, the pair came back to the store attempted to return the tablet.

Suspicious, Sears security investigated the product's packaging and found the box had been filled with rocks, and the tablet was missing, the Sun-Times reports. The teens then attempted to run from the store but were apprehended and arrested by police.

The men are scheduled to appear in court July 12.
