Federal agents in Los Angeles on Wednesday conducted the most high-profile immigration sweep in the area since a court order barred the authorities from stopping people for immigration checks without “reasonable suspicion.”

Whether the raid violated the court order is a question the judge in the case could be asked to consider in the coming days.

The Department of Homeland Security said that the operation, named Trojan Horse, was a “targeted raid” that led to arrests of 16 undocumented immigrants from Guatemala, Mexico, Honduras and Nicaragua.

Videos circulating on social media showed agents in tactical vests jumping out of a Penske rental truck in a Home Depot parking lot and then running onto the streets of the Westlake neighborhood, which is home to many Latino immigrants.

A wave of immigration raids in and around Los Angeles in June prompted days of demonstrations and led to a lawsuit asserting that federal agents were violating the Constitution in stopping people based on factors such as race, speaking Spanish and where they worked.

After a federal judge issued a temporary order barring such stops, large-scale sweeps in the Los Angeles area appeared to have fallen off, and last Friday, a three-judge appellate panel kept the order in place while the lawsuit moves forward in the lower court.
