Trump administration steps up immigration enforcement. BREAKING NEWS!

CHICAGO — Several Immigration and Customs Enforcement agents and other federal personnel waited in unmarked cars as they prepared to approach what they called their target.

According to ICE, Christopher Fragoso Lara, 25, of Mexico, had been convicted of home invasion, aggravated battery, domestic battery, possession of a weapon and other crimes. A surveillance team had spotted him Monday morning at the Chicago tire shop where he worked.

Agents shut down the street outside the business and arrested Fragoso Lara as he spoke to a customer outside, in subfreezing temperatures.

The arrest took place without incident when NBC News was embedded with the agents during operations throughout the Chicago area Monday morning. The enforcement agents departed downtown Chicago before sunrise and drove to Berwyn, a neighborhood on the outskirts of the city.

Three door-knocking operations did not result in arrests, but they demonstrated the time and manpower that goes into the operations. At each location, there were at least seven officers, from ICE and the Bureau of Alcohol, Tobacco, Firearms and Explosives, covering all the entrances and exits.

Ten teams of about 10 federal agents apiece fanned out across the city Monday, a source familiar with the operations said. The operations came during immigration enforcement operations in multiple cities around the country ordered by President Donald Trump.

The Trump administration has sought in the past week to publicly demonstrate that it is following through on Trump's promises to enact mass deportations immediately after having taken office. Arrest numbers last week remained on par with those in September, the latest month for which figures were available, until Friday, when numbers doubled.
