"Ban Islam from America" fliers left at a proposed mosque site in northwest Washington are under investigation.

The Herald reports (http://bit.ly/1rQlXDw) an anonymous tip led authorities to find an American flag Thursday near a damaged sign posted with the fliers.

The sign announced plans for the mosque.

Mukilteo police Officer Myron Travis says about a half-dozen paragraphs in the fliers contained "anti-Islamic rhetoric."

Mosque President Mohammed Riaz Khan says he's working with religious groups to schedule a meeting this month to answer the public's questions.

People can submit comments on the mosque plans until May 20.

Mayor Jennifer Gregerson said her community values diversity. She called the damage hateful and unacceptable.
