US border officials have launched an urgent hunt to detain a "vicious" illegal migrant who allegedly raped a 54-year-old woman in Chicago.
Immigration and Customs Enforcement (Ice) has filed an "arrest detainer" for Nicaraguan Leyter Jeferson Arauz-Medina - and has blamed Joe Biden for letting him roam free on American streets.
An arrest detainer urges local authorities to tip off Ice before Mr Arauz-Medina is released.
The agency said that doing so would stop him from "preying on more innocent women".
The migrant has been charged with rape, sex assault, assault, and drug possession after his alleged attacks on the woman on August 31.
He is accused of dragging the 54-year-old across the street while she screamed, forcing her into an alleyway, throwing her to the ground, strangling her and stripping her naked.
The Nicaraguan allegedly slammed the back of her head into the ground several times, rendering her unconscious.
When she came around, she kept fighting back as Mr Arauz-Medina continued his sexual assault.

The illegal migrant eventually fled the scene after being spotted by a passing motorist.
His alleged victim, meanwhile, was forced to run away naked looking for help before a food truck worker stepped in to rescue her.
Mr Arauz-Medina entered the US on September 17 last year near Eagle Pass, Texas, before being set free by the Biden administration.
An immigration judge ordered that he be deported on July 17 this year - just a month and a half before his alleged crimes.
Amid Ice's bid to take the "rapist" into custody, the Department for Homeland Security has warned that Illinois's Democrat Governor could let him walk free.

The DHS blasted Chicago's so-called "sanctuary city" status, saying it "rarely honours Ice detainers".
Its Assistant Secretary Tricia McLaughlin said: "A real-life nightmare: This criminal, who [Governor] JB Pritzker continues to protect, viciously attacked an innocent woman who was walking the streets of Chicago.
"This monster was released into our country by the Biden Administration.
"Governor Pritzker and his sanctuary policies protect criminal illegal alien rapists over American citizens. We will do everything in our power to ensure this wicked criminal never walks our streets again."
The Windy City has been a "sanctuary" since 1985. As part of that status, local law enforcement does not cooperate with federal immigration officials.
In February this year, the White House sued Chicago for "thwarting" attempts to enforce immigration law.
But that lawsuit was thrown out in July, with Mayor Brandon Johnson releasing a crowing statement in response.
"This ruling affirms what we have long known: that Chicago's welcoming city ordinance is lawful and supports public safety," Mr Johnson beamed.
"The city cannot be compelled to cooperate with the Trump administration's reckless and inhumane immigration agenda."
