U.S. Immigration and Customs Enforcement (ICE) agents arrested 115 people in the San Diego area this week in a three-day operation that began when President Trump Donald John TrumpBiden leads Trump by 36 points nationally among Latinos: poll Trump dismisses climate change role in fires, says Newsom needs to manage forest better Jimmy Kimmel hits Trump for rallies while hosting Emmy Awards MORE visited the region.

The Los Angeles Times reported Saturday that most of the arrests happened in San Diego County, but there were other arrests in nearby Imperial County.

The arrests involved undocumented immigrants who had criminal convictions, had been arrested on criminal charges, had been ordered to be deported or had returned to the U.S. after having been previously deported.

Forty-three percent of those arrested had criminal convictions, according to the Times. Most of them were from Mexico, though immigrants from Honduras, Guatemala, the Czech Republic, Kazakhstan and Peru were also arrested.

"Operations like this reflect the vital work ERO officers do every day to protect the nation, uphold public safety and protect the integrity of our immigration laws and border controls," said Greg Archambeault, the field officer director for ICE Enforcement and Removal Operations in San Diego.

"We will continue to conduct similar operations, while seeking to ultimately deport at-large criminal targets and other immigration fugitives who pose a threat to public safety."

He said it was a coincidence that the operation, which ended Thursday, started on the same day that Trump traveled to San Diego, according to the Times.

The immigration sweep came more than a week after the Trump administration sued to block three California state laws that the Justice Department says obstructs federal immigration officials from doing their jobs.

Archambeault said that such large-scale operations are not unique to the current administration, but noted that it had been a while since such a sweep was conducted in the San Diego area.
