US Immigration and Customs Enforcement (ICE) officers have reportedly been instructed to stop arresting immigrants who have no criminal convictions or pending criminal charges, according to agency sources cited in a report.

Under the reported directive, federal immigration agents would continue to arrest immigrants with criminal convictions or pending criminal charges. People with final deportation orders but no criminal convictions or pending charges would reportedly not be targeted for arrest.

The reported change would also end so-called “collateral arrests,” in which officers detain other undocumented immigrants encountered while pursuing a criminal suspect, according to the sources.

The reported directive comes amid heightened scrutiny of the Trump administration’s immigration enforcement policies and ICE operations. Some ICE officers have reportedly expressed frustration over the change.

One source suggested the directive could be connected to the upcoming US midterm elections, although this was presented as the source’s view and was not independently established in the report.

The development follows a recent incident in Texas in which an ICE officer shot and wounded a Venezuelan man during an attempted traffic stop. ICE subsequently reminded officers that body cameras must be activated during enforcement activities.

The reported directive could reduce the number of immigration arrests involving people without criminal records.
