Alberto Castañeda Mondragon is a 31-year-old Mexican immigrant who was assaulted and severely injured by ICE on January 8, 2026 in St. Paul, Minnesota.
Alberto entered the United States legally in 2022 and overstayed his visa while working as a construction worker. He used his earnings to support his elderly father, who is disabled and diabetic, and his 10-year-old daughter back home in Veracruz. His immigration status was unknown to ICE at the time of his arrest.
Details of Alberto Castañeda Mondragon’s Arrest and Assault by Immigration and Customs Enforcement Officers
ICE agents first encountered Alberto in the parking lot of a shopping center, where he was the passenger in a friend’s car. Castañeda Mondragon recalled being pulled from the car by the agents and thrown to the ground, where they proceeded to punch him and strike him with a steel baton.
Once detained, Alberto was put inside an SUV and taken to a detention facility, where he says he was beaten again. Hours later, ICE agents arrived at an emergency room in Edina, MN, claiming that he had “purposefully ran headfirst into a brick wall” while attempting to flee custody.
CT scans showed Alberto had at least eight skull fractures and life-threatening hemorrhages in five areas of his brain. The fractures were located at the front, back, and both sides of his skull — inconsistent with the story told by ICE regarding Alberto’s injuries. Court documents claim that when staff further questioned the officers about Alberto’s injuries, an officer stated he “got his shit rocked”.
Alberto was then transferred to Hennepin County Medical Center. At the time, he was alert and speaking and told hospital staff that he’d been “dragged and [beaten] by federal agents.”
His condition quickly deteriorated and by January 16th, a court filing described him as “minimally responsive and communicative, disoriented and heavily sedated.”
Tensions between hospital staff and ICE were high, exacerbated by the agents’ insistence to keep Castañeda Mondragon’s ankles shackled to his bed after he attempted to stand up.
A nurse tried explaining to the agents that Alberto’s behavior was typical of someone with a traumatic brain injury, and assured them he was not trying to escape. The disagreement escalated to the point where hospital security, the facility’s CEO, and hospital attorney became involved.
They reached a compromise that a nursing assistant would sit with Castañeda Mondragon to prevent him from leaving, and in return the shackles were removed.
Two weeks after his arrest, a U.S. District Court judge determined Alberto’s arrest was unlawful and ordered him released from ICE custody. He was released from the hospital days later and taken in by co-workers.
Lies and Misconduct By the US Government in Relation to Castañeda Mondragon’s Arrest and Assault
Immigration and Customs Enforcement Agency
Nature of Castañeda Mondragon’s Injuries
As detailed above, ICE officers told hospital staff that Castañeda Mondragon injured himself by deliberately running into a wall while trying to escape custody.
Medical scans and evaluations proved that his injuries were not consistent with those claims, and upon an independent review by physicians who were not involved with the case it was determined that ICE’s account of his injuries were impossible.
“I almost think one doesn’t have to be a physician to conclude that a person can’t get skull fractures on both the right and left sides of their head and from front to back by running themselves into a wall” said Dr. Lindsey C. Thomas, a board-certified forensic pathologist who worked as a medical examiner in Minnesota for more than 30 years.
Nature of Castañeda Mondragon’s Arrest
Castañeda Mondragon’s lawyers told a court that their client was racially profiled by ICE when he was arrested.
Officers only determined his immigration status after his arrest, meaning he was initially targeted based on his race. An ICE officer signed his arrest warrant when they arrived at the Bishop Henry Whipple Federal Building, so the agency did not have an arrest warrant signed by an immigration judge.
These claims were substantiated later when a U.S. District Court judge ruled his arrest unlawful and ordered his release from ICE custody.
Tricia McLaughlin, DHS Assistant Secretary for Public Affairs
Tricia McLaughlin doubled down on the agency’s lie, saying “On January 8, 2026, ICE conducted a targeted enforcement operation to arrest Alberto Castañeda Mondragon, a 31-year-old illegal alien from Mexico who overstayed his visa. While in handcuffs, Castaneda attempted to escape custody and ran toward a main highway. While running, Castaneda fell and hit his head against a concrete wall.”
Court filings proved that the arrest was not targeted, as Castañeda Mondragon’s immigration status was not determined until he reached the ICE detention facility.
Furthermore, medical records proved that the assertation Castañeda Mondragon injured himself was a lie.
