On September 28, 2011, U.S. Immigration and Customs Enforcement (ICE) announced that it arrested more than 2,900 convicted criminal aliens and fugitives during a 7-day “Cross Check” enforcement operation. The operation was carried out in all 50 states and four U.S. territories by ICE officers and agents in coordination with local, state and federal law enforcement agencies. All detained individuals had prior criminal convictions; more than half for felony violations. Additionally, 681 individuals were fugitives who had previously been ordered to leave the country but failed to do so; 386 individuals had previously been removed from the country multiple times and had illegally re-entered the U.S.
