FRESNO, Calif. (FOX26) — Reports of increased Immigration and Customs Enforcement activity are spreading across the Central Valley this week, with people being detained and families left searching for answers.Some of those detained are being taken to immigration detention facilities in McFarland, more than an hour south of Fresno.For one Fresno family, the experience has brought what they describe as “anguish” after their father was detained last week. The family says he has underlying health issues and they are concerned about his well-being while in custody.Across the Valley, videos circulating online appear to show masked ICE agents pulling people over and taking them away in unmarked vehicles.[RELATED] Video shows ICE arrests in West Park near FresnoElaina Salazar says her father, Luis Arreguin, was detained at about 5 a.m. last week while he was on his way to work.“No warrant, just working off of a tip, and they let him know that as he was being detained, ‘Hey, we know you didn't do anything wrong, but we're here.’”Salazar describes her father as loving and hardworking. At 54 years old, she says he has called Fresno home since he was five and is the person who provides for their family.“He did not commit a crime by being here. He loves this country. He loves us, and he just wants to be back with us.”Salazar says she is also concerned about the way her father is being addressed while in custody.“Referring to my dad as an alien or as a number is probably the most disrespectful thing I've ever heard.”Her concerns extend to her father's health. Salazar says he has high blood pressure and that his condition has been elevated for days.“He had a high blood pressure of 198 over 80 for multiple days. But too, if you deport my father in the middle of the night and you drop him off in Mexico, where he doesn't truly speak the language and he has no resources, and he dies there, what does that say about you? What does that say about the care for human beings?”Families seek answers as ICE activity spreads across Central ValleyAccording to federal Immigration and Customs Enforcement data cited by the family, 36 people have died in ICE custody during the 2026 fiscal year.Salazar says her father also worries about other people being held at the facility.“Every time I speak to him, he's talking about everybody else in the facility. He's saying, ‘I feel so bad for them. They get no visits, they get no calls. They can't afford to buy food. They're wilting away. They're alone, they're lonely. Their loved ones aren't documented, so they're not allowed to visit them.’”Congressman Jim Costa says he is aware of ICE activity in the Central Valley and is working with local and federal officials, as well as advocates, in response.Costa is also asking people to report immigration enforcement activity to his office.[RELATED] Mendota man detained by ICE in Fresno already transferred to Kern CountyFor Assemblymember Esmeralda Soria, the issue is personal.“As a daughter of immigrants, I am really terrified for families if, in fact, people are detained and are unlawfully detained.”Soria said that while her office cannot provide legal assistance, it can connect families with resources and information.For Salazar, the impact is already being felt at home.“You're ripping apart families. It's hard. It's unbelievable.”Salazar says her father was in the process of obtaining his citizenship before he was detained.For now, she is making the trip to McFarland three days a week to visit her father and wait for answers about what comes next.
