U.S. Immigration and Customs Enforcement (ICE) in conjunction with the Oklahoma Highway Patrol recently apprehended over 100 illegal immigrants as part of a three-day operation.

On October 6, the U.S. Department of Homeland Security (DHS) announced that the operation focused on “threats to public safety along I-40 in Oklahoma,” which occurred from September 22 to September 25.

“ICE conducted records checks on foreign-born nationals encountered by the Oklahoma Highway Patrol during the operation,” stated the DHS’s announcement. “This led to the detention of 120 illegal aliens for immigration violations, 91 of whom were found operating a commercial motor vehicle with commercial driver’s licenses (CDL).”

Among the 120 suspects, past convictions included DUIs, illegal re-entry into the U.S. and money laundering, as well as human smuggling and assault.

We urge more state and local law enforcement agencies to enter into 287(g) agreements to assist in removing public safety threats and to access reimbursement funds available for our law enforcement partners.”

The arrests came just weeks after a suspect, who was deported several times before, allegedly caused a DUI-related crash in California.
