CHICAGO (CBS) -- In the midst of the busy online holiday shopping season, a strange discovery was made in Chicago's Little Village neighborhood Saturday afternoon. 

A neighbor called police after he heard strange noises, then spotted a UPS truck in the alley. 

Then he noticed dozens of boxes dumped over a fence into a park behind his house. 

Officers were able to recover the packages. 

"I come out and look at the fence, and I see boxes all over," the man said. 

It's unclear if the truck or the packages were stolen. Police are still investigating what happened. 

CBS 2 has also reached out to UPS but had no response Saturday evening.
