A Michigan police officer is on administrative leave after a prospective buyer of his home said he found a framed Ku Klux Klan application and several Confederate flags inside the residence.

Rob Mathias, who is Black, was touring the home in the Muskegon County town of Holton with his wife and children last week when he said they discovered the racist memorabilia hanging on the walls.

Mathias said he would have still considered purchasing the home despite the flags, but the application caused him to gather his family and immediately leave the property.

“I’m still disgusted by it. I’m hurt,” Mathias, an Army veteran, told MLive. “You can’t serve your community and be a racist. You can’t. There’re people of all different colors, of all different nationalities ... out there that you have to serve and protect. You can’t just protect one group of people.”

Muskegon City Manager Frank Peterson identified the officer to Fox 17 News as 20-year veteran Charles Anderson and confirmed an internal investigation is underway.
