People hoping to drop off a card or mail a few bills this week at the U.S. Postal Service's Chickamauga Station on East Brainerd Road were met with a big empty spot where the drop boxes were previously.

Channel 3 received a few inquiries about the missing mailboxes and reached out to the Postal Service to find out what happened.

The blue mailboxes, used outside the facility for dropping mail, were damaged when they were broken into over the Labor Day weekend, explained Tad Kelley, a communications specialist for the U.S. Postal Service.

Kelley also said the USPS Inspection Service is investigating the incident.

Plans are to install new, secure collection boxes to replace the damaged ones.

Customers who feel that may have lost items they mailed by calling 1-800-ASK-USPS or visiting their website to file a complaint or inquiry.
