EXCLUSIVE — Federal law enforcement believes bounties placed on the heads of U.S. Immigration and Customs Enforcement sweeping the streets of Chicago originated in Mexico and that local gangs are actively trying to carry out the assassinations.

The Department of Homeland Security shared internal information from the Drug Enforcement Administration with the Washington Examiner on Thursday afternoon, stating how gangs in Chicago’s southwest neighborhoods were offered bounties between $5,000 and $50,000 for each ICE employee assassination.
