(KAIR)--No arrests are yet reported in what authorities call the possible desecration of gravesites “and other sacred properties of the [Prairie Band Potawatomi] Nation.”

The investigation was announced Saturday in a social media post by the Prairie Band Potowatomi Tribal Police Department.

In the post, the Tribal Police called on the public to “be on the lookout for a muddy silver pickup truck with Arkansas license plates driven by a white male in a ball cap.”

Anyone with information about the truck are asked to call 785-966-3024.
