Immigration arrests rose 32.6 percent in the first weeks of the Trump administration, with newly empowered federal agents intensifying their pursuit of not just immigrants with criminal records, but also thousands of immigrants who have been otherwise law-abiding.

U.S. Immigration and Customs Enforcement arrested 21,362 immigrants, mostly convicted criminals, from January through mid-March, compared with 16,104 during the same period last year, according to statistics requested by The Washington Post.

Arrests of immigrants with no criminal records more than doubled to 5,441, the clearest sign yet that President Donald Trump has ditched his predecessor’s protective stance toward most of the 11 million immigrants living in the United States illegally.

Advocates for immigrants say the unbridled enforcement has led to a sharp drop in reports from Latinos of sexual assaults and other crimes in Houston and Los Angeles and has terrified immigrant communities across the United States. A prosecutor said the presence of immigration agents in state and local courthouses, which advocates say has increased under the Trump administration, makes it harder to prosecute crime.

“My sense is that ICE is emboldened in a way that I have never seen,” Dan Satterberg, the top prosecutor in Washington state’s King County, which includes Seattle, said Thursday. “The federal government, in really just a couple of months, has undone decades of work that we have done to build this trust.”

A spokeswoman for ICE said her agency “remains sensitive” to victims and witnesses and helps them obtain visas or stays of deportation in some cases. But she said anyone in the United States illegally could be deported.

ICE “focuses its enforcement resources on individuals who pose a threat to national security, public safety and border security,” spokeswoman Jennifer Elzea said in a statement. “However, as (Homeland Security) Secretary (John) Kelly has made clear, ICE will no longer exempt classes or categories of removable aliens from potential enforcement.”

Nearly three-quarters of the immigrants arrested from Jan. 20 to March 13 had criminal convictions, an increase of 15 percent over the same period last year.

But the biggest spike is the arrest of immigrants with no criminal records, with immigration field offices in New York, Boston and other places doubling or tripling their numbers from last year.

ICE’s Atlanta office arrested the most immigrants who had never committed any crimes, with nearly 700 arrests, up from 137 the prior year.

The ICE field offices with the largest total number of arrests — more than 2,000 each — were in Dallas, which covers North Texas and Oklahoma; Atlanta, which includes Georgia and the Carolinas; and Houston, which spans Southeast Texas.

Immigration detainers — voluntary requests from ICE to law enforcement agencies to hold those arrested beyond their normal release so that agents can take them into custody and deport them — also rose, to 22,161. That was a 75 percent jump from the year before. But many were issued in areas that do not necessarily comply with ICE requests.

Overall, deportations are down by 1.2 percent, to 54,741 in January, February and March, compared with the same period last year. Elzea said it can take time to remove someone from the United States, but the number of noncriminals deported is higher this year, while the number of criminals who were deported fell.

Despite his pledge to send criminals packing, Trump has struggled to get countries such as China to take their citizens back.

Some say criticism of Trump’s policies seems politically charged, noting that President Barack Obama deported thousands of immigrants without criminal records. And arrests this year are lower than Obama’s first weeks in 2014, when agents arrested 29,238 immigrants, including 7,483 noncriminal ones.

The mayor of Miami-Dade County said in a recent interview that he has fielded more protests over the city’s immigration policies this year than under Obama.

“It’s all got to do with the president,” said Mayor Carlos Gimenez, a Republican who said he voted for Democrat Hillary Clinton in the presidential election. “Most of it has to do with politics. It’s sad.”

Advocates for immigrants say they also criticized Obama as the “deporter in chief” and waged a national campaign to create sanctuary cities to shield immigrants from deportation.
