Protesters gather on Chicago's Southwest Side after reports of masked ICE agents and arrests

Activists gathered Monday afternoon on Chicago's Southwest Side after reports of U.S. Immigration and Customs Enforcement activity and arrests.

The protesters responded to reports of masked agents spotted in the 3100 block of S. Damen Ave., and near 33rd and Wolcott in the city's McKinley Park neighborhood.

There were reports that agents arrested someone near Damen and the Stevenson Expressway.

The activists blew whistles and alerted residents to the agents' presence.

CBS News Chicago cameras caught several agents in the area wearing clothing that identified them as ICE.

Ald. Julia Ramirez (12th) confirmed that six people were detained during the activity. 

In a statement she said in part, "We will not allow ICE to terrorize our families and make fear a normal part of life in our neighborhoods. Every time they come into our community, we will organize, fight and protect one another. ICE is not welcome in the 12th Ward."

CBS News Chicago has reached out to the U.S. Department of Homeland Security for more information and is waiting to hear back.
