Nearly 500 criminal illegal aliens were arrested by U.S. Immigration and Customs Enforcement (ICE) in a four-day operation in sanctuary city jurisdictions, which shield illegal aliens from deportation.

Known as Operation Safe City, ICE agents detained a total of 498 illegal aliens living in sanctuary cities who violated U.S. immigration laws; have criminal convictions or pending criminal charges; are known gang members, immigration fugitives; and those who re-entered the U.S. after already being deported, according to ICE officials.

Illegal aliens who are currently shielded from deportation by the Obama-created Deferred Action for Childhood Arrivals (DACA) program were not targeted in the operation, though those individuals will become eligible for deportation as their temporary protected status expires over the next two years.

Of the illegal aliens arrested:

317 had criminal convictions

68 are immigration fugitives

104 are previously deported criminal aliens

18 are gang members or affiliates

The sanctuary cities targeted in the operation included:

Philadelphia, Pennsylvania (107)

Los Angeles, California (101)

Denver, Colorado (63)

Massachusetts statewide (50)

New York City, New York (45)

Portland, Oregon (33)

Cook County, Illinois (30)

Baltimore, Maryland (28)

Santa Clara County, California (27)

Washington, D.C. (14)

Acting ICE Director Tom Homan said in a statement that sanctuary cities’ protection of criminal illegal aliens is driving the federal agency to conduct focused operations in those major areas.

“Sanctuary jurisdictions that do not honor detainers or allow us access to jails and prisons are shielding criminal aliens from immigration enforcement and creating a magnet for illegal immigration,” Homan said. “As a result, ICE is forced to dedicate more resources to conduct at-large arrests in these communities.”

“ICE’s goal is to build cooperative, respectful relationships with our law enforcement partners to help prevent dangerous criminal aliens from being released back onto the streets. Non-cooperation policies severely undermine that effort at the expense of public safety,” Homan said.

ICE provided a chart of all the criminal convictions by the illegal aliens arrested.

Many of the illegal aliens arrested in the operation will face federal prosecutions for re-entering the U.S. after being deported, while others will be immediately removed.
