Police stop-and-frisk jumped more than 22 percent last year — the first increase under Mayor Bill de Blasio and the highest number of stops since 2015, a new report says.

The new data, released Friday by the NYPD, shows the controversial stops jumped in 2019 to 13,459 — up from 11,008 the year prior.

The NYPD attributed the increase to cops properly reporting stops due to improved training in the “very complex area of law.”

“It’s unlikely to be a true increase in stops but rather more accurate and complete reporting,” an NYPD spokesperson said.

The number is far less than the nearly 700,000 stopped at the height of the stop-and-frisk program under Mayor Michael Bloomberg. Civil rights groups called the new data “an alarming trend” under recently appointed Commissioner Dermot Shea — but the NYPD was unfazed.

In 2019, arrests were made in about one of every three stops — with counts of robbery, petit larceny, criminal possession of a weapon and assault accounting for the majority of the charges, the data shows.

Police found around 1,200 weapons — including 415 firearms — in just over 9 percent of stops, according to the report.

Cops collared 14 people on murder charges last year, the data shows.

Black or Hispanic people accounted for 88 percent of the people stopped last year, according to the data.

East New York logged the most stops out of any precinct, recording 495 stop-and-frisk incidents — but the 75th Precinct’s arrest rate was half the citywide average. Less than 16 percent of police stop-and-frisks in the precinct yielded arrests.

A federal monitor overseeing the NYPD’s use of the policing practice previously dinged cops for not properly recording the stops.

Opponents of the practice, who have challenged the policy as discriminatory, were not reassured by the department’s response.

“This is an alarming trend at the beginning of Commissioner Dermot Shea’s tenure but not surprising as he is a long-time champion of discredited broken windows policing,” said Corey Stoughton of the Legal Aid Society.

“This data confirms what we hear from our clients on a daily basis — despite court rulings that the City’s practices were unlawful, aggressive stop-and-frisk has made a comeback in New York City.”

Chris Dunn, legal director of the New York Civil Liberties Union, called the new numbers “worrisome.”

But Dunn added, “Our bigger concern is that large numbers of stops simply are not being reported by officers. In truth, tens of thousands more New Yorkers may be the victims of stop-and-frisk than these figures suggest.”

The contentious policing tactic was a key part of the Bloomberg administration, which peaked in 2011 with nearly 700,000 stops recorded. The policy was eventually challenged in a federal lawsuit — Floyd v. City of New York — that ended with a judge ruling the practice was being used in an “unconstitutional” manner because it led to “indirect racial profiling”

Bloomberg apologized for his administration’s use of the tactic, calling it a “misguided policy” last year as he prepared to enter the Democratic presidential race.

De Blasio, who has touted the significant reduction in the practice over his tenure, said Monday at a press conference “I think there was some under-reporting and now we’re seeing the accurate number.”

“A stop is used occasionally now … when it is mandated or when it is suggested by very specific conditions. That’s the way it’s supposed to be,” Hizzoner added.
