The New York Police Department is partnering with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) in an effort to reduce gun violence in the New York City

The NYPD's crime statistics portal shows a 77.4% rise in shootings so far in 2021 compared to the same time period in 2020, as well as a 76.9% increase in the number of shooting victims year-over-year (637 in 2021 compared to 360 in 2020).

"This is crucial. Everyone agrees," New York City Mayor Bill de Blasio said of the partnership, which he described as "unprecedented," during a Tuesday press briefing.

"The number one issue is guns getting the guns off our streets. And we all know that the proliferation of guns during the pandemic was unprecedented and troubling. And therefore, we have to double down on getting guns off our streets," he said.

He added that the ATF "finds the guns, gets them out of the hands of bad guys and keeps communities safe."

"We know that gun trafficking must be attacked on a national level, and the ATF leads the way," the mayor said.

It will be the first time in history that the ATF has partnered with a local police department. ATF agents will be "directly embedded in the NYPD working together to find guns and quickly act on the information that they find to stop the flow of guns," he continued. 

ATF told Fox News in a statement that its "Crime Gun Intelligence Centers (CGIC) serve as intelligence hubs and coordination centers for local, state and federal responses to mass shootings and other major crimes involving firearms."

"The New York Field Division’s CGIC is now co-located with the New York City Police Department’s (NYPD) High Intensity Drug Trafficking Areas program (HIDTA), to better incorporate intelligence gathering and disseminate the collective resources of ATF, NYPD and HIDTA with one common goal of reducing firearm related crimes," the Bureau said.

While each ATF Field Division surrounds a CGIC, "New York’s implementation stands out due to the unprecedented level of support and access to intelligence."

"The combined resources of ATF, NYPD, and HIDTA will allow us to more quickly identify and remove violent criminals and stop the illegal flow of firearms to the community," the Bureau said.  "This new approach of a unified command structure make New York’s implementation a sustainable gun violence reduction strategy and a model for intelligence sharing and violent crime reduction partnerships."

City police have been working since the summer of 2020 to address an uptick in violent crime in the city.

On the weekend ending May 23 alone, 27 people were shot in 22 shootings across the Big Apple, according to authorities and reports. 

In addition to gun violence, the NYPD told Fox News on May 24 that there had been four more stabbings or slashings in the subway system so far this year compared to the same time in 2020 as of May 16, with 64 reported year-to-date in 2021. The number of stabbings and slashings reported citywide was down by 2.1%, or by 29 incidents, the department said. 

De Blasio announced in mid-May the city would be deploying 250 more officers to the subway system, marking the "largest NYPD Transit force in over 25 years," he said at the time. The additional 250 officers will be deployed on top of the 3,000 officers previously assigned to the subways, the mayor said.
