There's a new police commissioner at One Police Plaza, but the NYPD says crime numbers keep falling. NY1's Jose Martinez filed the following report.

James O'Neill's first full day as police commissioner was marked by the Chelsea bombing. But delivering his first monthly crime statistics briefing since taking over for Bill Bratton proved to be far more routine, with the news that crime in the city continues falling from a year ago.

"New York City continues to see significant declines in crime," O'Neill said.

Heralded as the safest September in more than two decades, overall crime fell more than 12 percent from the same time a year ago, with 2,333 fewer crimes reported this than in the first nine months of 2015.

"We finished down in every seven major crime category," said Dermot Shea, NYPD deputy commissioner for operations. "Every borough of New York City was down, too, which we're especially proud of."

There were 220 fewer robberies in September from a year ago, a drop of 14.3 percent. Burglaries plunged by nearly 25 percent, with 338 fewer this year than last. And car thefts dropped by nearly 23 percent, with 176 fewer than in 2015.

One troubling figure pointed out by police brass is the increase in the number of assaults on police officers.

"Up 191 assaults on our officers this year, and that's a 23 percent increase," Shea said. "So you see evidence again, further evidence, our officers putting themselves in harm's way."

Shootings are up, too, by 10 percent, with police officials blaming the increase on a surge in gang activity in parts of Queens and Brooklyn.

The FBI reported last week that nationally, violent crime is up close to 4 percent from a year ago, though still at far lower levels than it was a decade ago.

"We know how hard the leadership of those cities are working to address the situation," said Mayor Bill de Blasio. "We're very pleased to be in a city where crime continues to go down."
