An Ashwaubenon police officer has been investigated for wearing thong underwear at a charity event last summer.  The Public Safety Association says questions were asked about whether what Officer Jamie Zynda was wearing was appropriate.  Pictures and a video were studied.  No action was taken against Zynda, though he was told to review the department’s harassment policy.  In response, a grievance has been filed against the Ashwaubenon Public Safety Department.
