Louisiana police are investigating an anti-Muslim flyer pasted onto a sign in front of a mosque.

Bossier City spokesman Mark Natale (nah-TAH-lee) 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.

KSLA-TV reports (http://bit.ly/2kys7ET ) that the Council on American-Islamic Relations is asking authorities to investigate the placement of the flyers as a hate crime.
