Copies of a Ku Klux Klan newspaper were found in a Windham dry cleaning store Friday, WCSH-TV reported.

The station said an employee of Pratt Abbott found at least 10 copies of The Crusader, which is published by the Knights Party, or KKK.

Store officials told the Portland television station that no one knows how the papers got into the store and they were promptly thrown out after being discovered.

“We don’t support this cause or condone it. We are open to the public, so people come in use our facility and unfortunately someone left something behind,” David Marchesney, the owner of the dry cleaning chain, told WCSH.
