Authorities in three states have made arrests in connection with individuals impersonating Immigration and Customs Enforcement (ICE) officers, as tensions rise amid a nationwide immigration crackdown.

On Monday, the Florida Highway Patrol conducted a joint operation with federal immigration officers in Jefferson County to round up 12 people believed to be in the country illegally, one of a number of raids performed around the country as the Trump administration ramps up its plans for mass deportation.

Some people caught in Trump administration immigration operations have already been released back into the United States on a monitoring program.
