A 30-year-old undocumented migrant was forcibly detained by U.S. Immigration and Customs Enforcement agents on Tuesday after seeking refuge inside a medical clinic.
Denis Guillen-Solis, 30, had been landscaping outside the Ontario Advanced Surgery Center in Ontario, California, alongside two other alleged undocumented men when ICE agents arrived to serve an arrest warrant.
Upon noticing the officers, Guillen-Solis attempted to flee, running into the medical facility in search of safety.
The federal immigration agents then followed him inside, where a tense and chaotic scene unfolded.
In a video of the confrontation, medical staff, some in scrubs, can be seen and heard telling the agents they were trespassing on private property without a warrant and demanding that they release Guillen-Solis.
The two ICE agents, both with faces covered, attempted to pull Guillen-Solis from a doorway inside the clinic as he clung to the doorframe, sobbing and resisting.
Staff repeatedly asked the agents for identification, a badge, or a warrant, but according to witnesses, who claim none was provided.
Javier Hernandez, a member of the Inland Coalition for Immigrant Justice – an organization advocating for the rights of immigrants – told KTLA that the agents never identified themselves.

‘They basically just started running after him,’ Hernandez said. ‘[Solis] then ran inside of the clinic where they were working to seek shelter.’
In a statement issued after the incident, Department of Homeland Security Assistant Secretary Tricia McLaughlin accused clinic staff of assaulting federal officers and dragging both an agent and Guillen-Solis into the facility, CBS News reported.
McLaughlin also alleged that staff locked doors, blocked law enforcement vehicles, and called local police claiming a kidnapping was in progress – actions she described as attempts to obstruct the arrest.
Hernandez disputed those claims, defending the clinic employees’ actions as lawful and ethical.

‘They were doing their job, they were protecting themselves, they were exercising their rights to ask who these gentlemen were,’ he said.
‘They did not impede them from leaving.’
Hernandez added that Guillen-Solis has lived in the U.S. for the past three years, working as a landscaper to send money home to support his ailing mother in Honduras.
Since his detention, he has reportedly been allowed only one phone call to family members.
‘People are getting abducted,’ Hernandez said. ‘We lose them for two, three days, maybe a week or two, and we don’t know where they are at. That is not normal and we should be fighting back.’
No one from the surgery center was taken into custody. It remains unclear whether any charges will be filed against clinic staff.
As for Solis, whose family has organized a GoFundMe to help with the cost of legal fees, he is being held downtown at the federal detention center, according to KTLA.
