The Pima County Sheriff’s Department is sponsoring a free shred-a-thon Saturday to help combat identity theft.

From 8 to 11 a.m. Saturday — or until the disposal trucks fill up — county residents can have up to five boxes of documents and paperwork shredded for free on-site.

The drive-through service is at Casas Church 10801 N. La Cholla Blvd., between West Naranja Drive and West Lambert Lane, on the northwest side.

Documents will not be accepted from commercial businesses.

For more information, call the sheriff’s community resources unit at 351-4615.
