Almost 1,300 of the detainees had multiple convictions to their name and came from 115 countries. Types of convictions included manslaughter, attempted murder, kidnapping, armed robbery, drug trafficking, child abuse, sexual crimes against minors and aggravated assault.  The majority (2,642) of those detained  were men.

Noth stateside and regional “Cross Check” operations have been taking place periodically since December 2009.

"The results of this targeted enforcement operation underscore ICE's ongoing commitment and focus on the arrest and removal of convicted criminal aliens and those that game our nation's immigration system," ICE director John Morton said in a statement.

"Because of the tireless efforts and teamwork of ICE officers and agents in tracking down at large criminal aliens and fugitives, there are 2,901 fewer criminal aliens in our neighborhoods across the country."
