Federal immigration agents arrested 23 people in the Portland area in a three-day operation spanning the Pacific Northwest that ended Monday, Immigration and Customs Enforcement officials said Thursday.

ICE spokeswoman Rose Richeson said 84 undocumented immigrants were arrested in Alaska, Washington and Oregon, and 60 of them had criminal histories.

Seven people were arrested in Multnomah County, 13 in Washington County and three in Clark County, according to numbers provided by Richeson.

The operation targeted people who pose public safety threats and those who have violated federal immigration law, Richeson said.

Driving under the influence was the most serious criminal conviction for 19 of the 84 arrested, according to Richeson.

Some of those arrested had previous convictions for sex crimes, drug offenses and domestic violence, Richeson said. One person was charged with child rape, Richeson said.

Here is a breakdown of the convictions, according to Richeson:

CRIMINAL CONVICTIONS*

*Note: arrestees with multiple prior convictions are categorized based on their most serious conviction.

At least three people who grew up in the Portland area were arrested during the operation, according to immigration rights groups. Emmanuel Ayala Frutos, 21, and Francisco Rodriguez Dominguez, 25, were both arrested Sunday.

Both have received deportation deferments through the Deferred Action for Childhood Arrivials program. The program, established under the Obama administration, protects undocumented immigrants brought to the country at a young age.

Ayala Frutos' DACA expired two weeks ago. He was in the process of renewing it.

Rodriguez Dominguez was released from detention on bail Monday.

Immigration agents also arrested a Beaverton resident who was brought to the country from Guatemala when she was a 1-year-old, her lawyer said. Alejandra Ruiz-Matias was arrested Sunday, lawyer Stephen Robbins said.

Immigration agents asked Ruiz-Matias to visit their local office, Robbins said. When she arrived, they told her she had a deportation order from 1988. She would be detained and deported to Guatemala within a week, they said, according to Robbins.

Ruiz-Matias did not know about the deportation order, Robbins said.

Immigration authorities should have scheduled regular check-ins with Ruiz-Matias to sort out her case instead of detaining her, Robbins said.

Another "Dreamer," as DACA recipients are often called, was arrested at the Washington County Courthouse last Thursday, according to his lawyer. Luis Gerado Zuzueta, 21, was recently been charged with driving under the influence of intoxicants, lawyer Maria Zlaveta said. He was at the courthouse for a hearing when immigration agents arrested him, she said.

Zuzueta hadn't renewed his DACA since 2014, after he was convicted of delivering marijuana, Zlaveta said.

Zuzueta has lived in Hillsboro since he was a young child, Zlaveta said.

"If he has to leave, which is a very strong possibility, he'll have to start from scratch in a foreign country," she said.

Zuzueta is currently being held in a federal detention center in Tacoma, Zlaveta said.

Immigration rights groups have decried tactics used by immigration authorities, calling them brutal and inhumane.

Since Sunday, the immigration rights group Causa has received dozens of calls from Oregonians panicked that their loved ones have been detained, Executive Director Andrea Williams said Wednesday.

"When ICE uses these types of brutal tactics, it just makes people who are part of our communities more scared to live their daily lives," Williams said.

This report will be updated.
