CHARLOTTE, N.C. -- Several businesses owners in a South Charlotte shopping center have a major clean-up on their hands.

We found at least seven businesses, including a post office, were tagged with graffiti sometime between Thursday night and Friday morning. The vandals even spray-painted business trucks and vans.

Police officers told the business owners they weren't sure if the markings were gang-related.

Business owners plan to meet to come up with solutions to avoid being targets again.
