Federal immigration agents detain man at Prospect Heights apartment complex: VIDEO

PROSPECT HEIGHTS, Ill. (WLS) -- Federal agents gathered outside of a Prospect Heights apartment complex just before 10 a.m. Monday.

As the agents dressed in uniform walked on the property, numerous residents blew whistles and recorded video on their phones. The idea is to warn people that the agents are nearby and to document their actions.

"They see somebody outside and they just take 'em. No questions asked. It's just done," said activist Aileen Lopez.

A sign outside the complex warns unwelcome visitors to stay away. But the agents paid it no mind.

It is unclear who they were possibly looking for, but a few minutes after 10 a.m., they took a man into custody. Friends said he does not live there but was stopping by to give a coworker a ride to work.

One woman, who wants only her first name, Adriana, used, was recording from her balcony.

"They don't care if you're a citizen or not. They just grab whoever they want to grab," Adriana said.

The Department of Homeland Security did not immediately return ABC7's requests for information.

Activists say the raids have a tremendous impact on the community.

"We don't see kids playing anymore. The parents are scared to pick up their kids from the school bus stop. It's very sad," said activist Francisco Ruiz.

Communities throughout the northwest suburbs are considering laws that would ban federal immigration agents from being on city property without an arrest warrant.

The latest meeting happened on Monday night in Wheeling, where the village board passed a resolution banning the use of village property for immigration efforts.

However, the resolution does not apply to private property or public areas, including streets. The resolution takes effect immediately.
