DHS says its latest ICE arrests targeted people convicted of serious crimes. But Southern California’s broader enforcement data show a more complicated picture—and California’s sanctuary laws do not prevent federal immigration arrests.
The Department of Homeland Security says U.S. Immigration and Customs Enforcement arrested people it describes as “criminal illegal aliens” across the country over the weekend, highlighting individuals the agency says were convicted of serious crimes.
But for immigrant families in Southern California, the more important question is not simply who DHS says was arrested.
It is what the latest federal enforcement push means for people living in Los Angeles and surrounding communities—and what families should know about their rights.
What did ICE announce?
In an August 10 release, DHS said ICE arrested people nationwide who had been convicted of crimes including murder, sexual offenses, drug trafficking and other offenses. The agency presented the operation as part of its effort to target people it considers serious public-safety threats.
DHS is describing the people arrested and the purpose of the operation from the federal government’s perspective. The announcement does not independently establish that every person arrested during the weekend had a criminal conviction, nor does it provide a complete public breakdown of every arrest.
That distinction is especially important in Southern California, where available data show that ICE’s broader enforcement activity has involved people with very different immigration and criminal histories.
Was Southern California part of the August 10 operation?
The DHS announcement does not identify Los Angeles or Southern California as a location included in that specific weekend operation.
That does not mean ICE activity has stopped in the region.
Southern California has experienced extensive federal immigration enforcement over the past year, including workplace and community arrests. An LAist analysis of federal data found that ICE made 14,394 arrests in the greater Los Angeles area in 2025, compared with 4,681 in 2024.
The region also remains home to the Adelanto ICE Processing Center, where immigrant detainees have continued to face litigation and scrutiny over detention conditions.
So families should distinguish between the specific August 10 announcement and the much larger immigration-enforcement campaign that has been underway in Southern California.
Who has ICE been arresting in Southern California?
This is where the picture becomes more complicated than the federal government’s latest messaging suggests.
According to the Deportation Data Project, an initiative involving UCLA and UC Berkeley researchers that uses federal immigration-enforcement data obtained through public-records requests and litigation, 69% of 722 people arrested by ICE in the Los Angeles region during June 1–10, 2025, had no criminal conviction. Fifty-eight percent had never been charged with a crime.
A larger analysis of 2025 Los Angeles-area arrests found that 46% of those arrested had criminal convictions, 15% had pending charges and 39% had neither criminal charges nor convictions.
Researchers at UCLA have also found that arrests of people with no criminal convictions, pending charges or identified gang affiliation became a much larger share of ICE arrests during the Trump administration.
These numbers do not prove that people without criminal convictions were part of the particular August 10 operation announced by DHS.
They do show why the word “criminal” requires context.
An ICE arrest is an immigration-enforcement action. A person can have an immigration case without having a criminal conviction.
For Southern California families, that distinction can be significant.
What does California’s sanctuary law actually protect?
California’s sanctuary protections limit how much state and local law enforcement can assist federal immigration enforcement. The state’s primary sanctuary law, SB 54, the California Values Act, generally restricts state and local agencies from using their resources to investigate, arrest or detain people for federal immigration-enforcement purposes, with specified exceptions.
But sanctuary protections do not prevent ICE from enforcing federal immigration law in California.
In other words:
California sanctuary law does not mean ICE cannot make arrests in California.
It means state and local law enforcement agencies face restrictions on how they can cooperate with federal immigration authorities.
The California Attorney General’s Office says state and local law enforcement generally cannot investigate or interrogate people for immigration enforcement, make arrests based on civil immigration warrants, or assist immigration authorities in specified activities, subject to exceptions established by law.
California has also continued updating guidance for public institutions as federal immigration enforcement has intensified, including new policies affecting schools and other public agencies.
What should Southern California families know?
Families should not assume that having no criminal conviction automatically means they cannot be detained by ICE.
At the same time, families should not assume that California’s sanctuary laws offer no protection.
The two systems operate differently.
California can restrict what state and local agencies do. It cannot simply prohibit federal immigration authorities from enforcing federal law.
The California Attorney General’s Office maintains a multilingual Know Your Immigration Rights resource explaining protections available to immigrants in California, including information about law enforcement interactions and access to legal assistance.
Families facing an immigration matter should also be cautious about legal advice from unlicensed individuals or immigration “consultants.” The Attorney General’s Office warns that immigration scams can cost families thousands of dollars or damage an immigration case.
For people already dealing with detention or immigration court, obtaining qualified legal assistance can be especially important. A recent California program highlighted the continuing problem of immigrants navigating immigration court without legal representation.
DHS’s August 10 announcement presents the latest ICE arrests as a crackdown on people convicted of serious crimes.
But that announcement should not be interpreted as a complete picture of who ICE has been arresting in Southern California.
Available regional data show that ICE’s broader Los Angeles-area enforcement has included people with criminal convictions, people with pending charges and people with no criminal charges or convictions.
And while California’s sanctuary laws limit cooperation between state and local agencies and federal immigration authorities, they do not prevent ICE from conducting federal immigration enforcement in the state.
For Southern California immigrant families, the most useful takeaway is simple: do not rely on a federal press release—or a rumor about sanctuary protections—to determine what your rights are.
Know the difference between federal ICE authority and California’s limits on local cooperation, understand your legal rights, and seek qualified legal assistance when an immigration case affects your family.
