She said when she asked the agents if they had a warrant to make an arrest at the medical center, they would not respond and shoved her.

Fuentes said she was later handcuffed and threatened with arrest.

“This is violence,” Fuentes said.

Fuentes said there was an increase in immigration enforcement activity Friday in Humboldt Park.

She said tear gas was used on passersby at the Home Depot on Cicero Street and Armitage Avenue and at Rico Fresh on Armitage and Central Park Avenue, as well.

Several Chicago aldermen spoke out Friday, amid “ongoing militarized immigration enforcement in Humboldt Park.”

Fuentes, state Sen. Graciela Guzmán, Cook County Commissioner Jessica Vásquez, Alderman Anthony Quezada, Alderwoman Rossana Rodríguez-Sánchez and the Illinois Coalition for Immigrant and Refugee Rights are expected to speak out Friday outside Humboldt Park Health’s emergency room.

There has been an increased presence of federal agents across much of Chicago recently.

In the Back of the Yards neighborhood, many people were around when at least five men were detained Thursday.

This comes as the Department of Homeland Security says it has made more than 900 arrests so far across Illinois in “Operation Midway Blitz.”

There was also an immigration raid in Humboldt Park about 6 a.m. Thursday morning. A woman says federal agents knocked down her front door.

She says her husband and two other men in the home were detained by United States Immigration and Customs Enforcement.

The woman says she is a migrant from Venezuela, and her family has been in the U.S. for three years now, as they’ve been going through the process of seeking asylum.
