Matthew Albence, the acting director of the U.S. Immigration, Customs and Enforcement Agency, came to New York from the nation's capitol for one reason: to scold Mayor Bill de Blasio. 

"Make no mistake, it is this city's sanctuary policies that are the sole reason this criminal were allowed to roam the streets freely and end an innocent woman's life," Albence said.

A 92-year-old woman's death is on the city's hands, the nation's top immigration official said. 

Maria Fuertes died earlier this month after she was sexually assaulted on the streets of Queens. A 21-year-old undocumented  Guyanese man, Reeaz Khan, is charged in the case. 

ICE officials say they wanted to take Kahn into custody in November, weeks before the alleged murder. Kahn had been arrested for assault. 

ICE asked the NYPD to detain him. The NYPD did not. 

"These are preventable crimes, people, and, more importantly, preventable victims," Albence said. "There should be nothing political about removing dangerous recidivist criminals from our streets."

For 37 minutes on Friday, Albence railed against the de Blasio administration's sanctuary city policy. He spoke with NY1 afterwards.

When asked if he came up specifically to talk about this case, Albence answered, "Absolutely. It's the sole reason I am here."

NYPD will only honor ICE detainer requests for convictions of serious and violent crimes. ICE officials say that happened only about 10 times in the last year. 

In response to the press conference, de Blasio's press secretary tweeted that the death was an absolute tragedy, but she added that fear, hate and attempts to divide are signatures of the Trump administration, and the city must reject these lies.

In response to the idea that this is fear-mongering, Albence said, "I think the evidence we have seen out there should be causing fear, the fact that criminals are being released back out in the street. I am not a politician. I dont need anyone's vote."

"I am here to let the people of this city know, the policies of this city and this administration has make them less safe," he added.

Considering this isn't the first time the Trump administration and the de Blasio administration have tustled over sanctuary cities, it seems unlikely the city's policy will change.
