New NYPD crime statistics released Monday show a spike in shootings in recent weeks. The increase is forcing the police commissioner to speed up a summer anti-crime program, and it's putting new pressure on the mayor to approve the hiring of more officers. NY1’s Dean Meminger filed this report.

As the weather heated up over the last month, so did the gunfire across the city. 

"They are occurring more and more in the same neighborhoods. We are starting to see them in areas of northern Manhattan, we are seeing them in the Central Bronx and we are seeing them in Brooklyn north," says Deputy Commissioner Dermot Shea.

In the last four weeks,128 people have been shot. That's up 33 percent over the same period last year.

So far in 2015, 404 people have been shot, an increase of nine percent from last year at this time. 

Murders are up 10 percent this year as well. The NYPD is reacting, moving more officers into the streets, especially in the 15 precincts with the most violence.

The “Summer All Out” program, which moves officers in desk jobs to patrols, will begin June 8—a month earlier than last year.

"We are in the process of identifying up to 400 people to put out for the summer. And as we move into the summer months we will have a summer violence reduction overtime program. And that's not only going to be uniform suppression; there is an investigative component to that also," says Chief of Department James O’Neill.

The intelligence bureau also has just put together a violence and reduction plan for each precinct, detailing who's causing the most trouble.

"What are the most likely five threats and drivers that will be pushing gun violence within that command—whether that's an individual or whether that's a crew or whether that's a location that has become violence prone," says Deputy Commissioner John Miller.

Last week, Mayor Bill de Blasio didn't include any money in his proposed city budget to increase the number of officers on the force. Police Commissioner William Bratton says he and the city council will keep pushing.

"Let's make it very clear: I am looking for a lot more police officers. Let's make no mistake about that. The City Council has their number. I have my number. We are in discussions with the mayor," says Bratton.

Bratton says he really needs extra officers to help protect the city from terrorists.
