BOSSIER CITY, La. (AP) - Louisiana police are investigating an anti-Muslim flyer pasted onto a sign in front of a mosque. Bossier City spokesman Mark Natale says the letter-sized flyer reads "Imagine a Muslim-free America." Natale says a second flyer reading "What made America great: Blood and Soil" had also been stuck onto the brick sign.
    
He says both flyers carry the name American Vanguard, which identifies itself on its website as a white nationalist group. The Southern Poverty Law Center has identified it as a white supremacist group. Natale says identical flyers are available on the organization's website. American Vanguard did not immediately respond to an emailed query.
