According to CBS News
, 347 of the people arrested for illegal immigration had prior crime convictions. Having these convictions makes them eligible for deportation.
The arrests in Illinois, Indiana, Wisconsin, Kansas, Missouri, Michigan, Ohio, Iowa, Minnesota and Nebraska were part of the agency's "Cross Check" operations that began in 2009 and are being held across the country, now in the Midwest.
It was the latest in the last year in the series of similar enforcement operations held by ICE.
Most of the people who had prior crime convictions were convicted for serious violent crimes, such as aggravated assault, armed robbery, and drug trafficking. Some of those arrested were affiliated with gangs, and sexual crimes against minors.
The operation, which ended Thursday, was the largest of its kind for the agency, according to ICE
"The record number of arrests made during this operation is a direct result of excellent teamwork among federal agencies who share a commitment to protect public safety," said ICE Director John Morton. "ICE is focused on arresting convicted criminals who prey upon our communities, and tracking down fugitives who scoff at our nation's immigration laws. The results of this operation demonstrate ICE's commitment to those principles."
Largely as a result, ICE has so far this fiscal year removed a total of 142,526 criminal aliens from the United States, which is a record number.
