A new report reveals that dozens of criminal illegal immigrants shielded by New York City's sanctuary policy were released from jail and quickly rearrested for new crimes.

According to U.S. Immigration and Customs Enforcement (ICE), 440 criminal aliens were released from New York's jails between January and April despite having ICE detainers placed against them. Of those 440, 40 have already re-offended and been rearrested, ICE said.

“In just three months, more than three dozen criminal aliens were released from local custody. Simply put, the politics and rhetoric in this city are putting its own communities at an unnecessary risk,” said Scott Mechowski, acting field office director for ICE Enforcement and Removal Operations (ERO) in New York.

On "Fox & Friends," New York State Assemblyman Kieran Lalor (R) said sanctuary policies are a gift to criminals that only put legal citizens and law enforcement at risk.

"New York City police have already done the risky work of arresting these people. It's expensive, they put their necks on the line, they've brought them in. Now they're released. ICE has to go back out into the community, in some cases guns drawn, into dangerous situations and rearrest them," Lalor said.

"It's unnecessary risk, it's wasteful, it encourages illegal immigration, something we shouldn't be doing."
