Aurora Man Sentenced To Federal Prison For Attacking ICE Officers, Deputy

An undocumented immigrant from west suburban Aurora has learned his fate after assaulting federal immigration officers and a sheriff's deputy during an arrest last summer, prosecutors said.

Francisco Javier Acevedo-Caldera, 40, of Aurora, was sentenced to 12 months in federal prison after pleading guilty to assaulting a federal employee, according to court records.

The incident occurred on July 17, 2025, inside the lobby of the Kane County Sheriff's Department in St. Charles. Two U.S. Immigration and Customs Enforcement officers approached Acevedo-Caldera, who had recently bonded out of jail, with an arrest warrant, prosecutors said.

He resisted, kicking one officer, headbutting another and biting a Kane County sheriff's deputy who tried to help. The bite broke the deputy's skin, according to prosecutors.

Officers were eventually able to restrain him and carry out the arrest.

Prosecutors Cite Serious Conduct

In a sentencing memo, Special Assistant U.S. Attorney Sarah Finch described the confrontation as serious.

"Defendant's conduct was serious—he made physical contact with all three officer victims and caused bodily injury to two of them," Finch wrote.

"Assaulting these officers in a government building caused risk to public safety and demonstrated disrespect for the law and law enforcement."

Acevedo-Caldera pleaded guilty to a federal charge of assaulting a federal employee in January 2026, according to the U.S. Attorney's Office, Northern District of Illinois.
