Workers at a Des Moines recycling plant recovered thousands of dollars wrapped in old newspapers that were nearly shredded.

KCCI-TV reports workers at International Paper's Des Moines Recycling Center found the money Wednesday stuffed into an envelope that was wrapped inside newspapers.

Des Moines police Sgt. Jason Halifax says the fifty and one hundred dollar bills were clipped together with old, rusty paper clips.

Police wouldn't give an exact figure on the amount of money found but say it's tens of thousands of dollars.

Halifax says a worker noted the envelope as workers were getting ready to shred some paper. Employees stopped a machine and recovered the money.

Workers called police, who are trying to track down who brought in the newspaper.
