An innocent 17-year-old New Jersey girl was shot in Sunday night’s chaos outside Manhattan’s historic Stonewall Inn after the Pride parade — while the 16-year-old who nailed her ended up accidentally shot herself by a pal, authorities said.

The mayhem erupted around 10:15 p.m. when the 16-year-old, who was hanging with her own crowd, opened fire at a guy standing with another group on Sheridan Square just around the corner from the LGBTQ+ landmarked bar in Greenwich Village, cops said.

“It appears from video that these two groups know each other,” NYPD Chief of Detectives Joseph Kenny told reporters Monday. “As the two groups begin to separate themselves from the large group, a female, 16 years old, weaves her way through the crowd.

“It is clear that she is targeting a specific male,” Kenny said.

“This female then produces a 9 millimeter pistol, places it inches away from that male’s head, and pulls the trigger two times,” the police official said.

“By some miracle, this male is not shot.”

But one of the slugs ended up traveling about 100 feet, striking the uninvolved 17-year-old girl, who was visiting from Bayonne and was with a friend at the time.

The bullet traveled through the teen’s left thigh and lodged in her right thigh, according to Kenny.
She was taken to Northwell Greenwich Village Hospital with non-life-threatening injuries, cops said.

“She had no connection to the shooter, and she had no connection to the previous fight that was taking place,” the chief said. “She was in New York City to celebrate the Pride parade and was a total innocent bystander.”

A male in the shooter’s group then fired at their rivals a second time — and mistakenly hit the pal who fired the first shot, striking her in the head and gravely wounding her, Kenny said.

The shooter-turned-victim was about 10 feet away from the gunman, who appeared to be recklessly “airing out” his weapon into the crowd, firing about four rounds, according to Kenny.

The 16-year-old, who is from Brooklyn, was rushed to Bellevue Hospital, where she was listed in critical condition, Kenny said.

Her own weapon was recovered on the ground right next to her, authorities said.

The younger teen’s mother answered the door at her Fort Greene apartment Monday but declined to answer any Post questions, only saying, “She’s OK” and, “I’m not speaking to anyone right now.”

Food carts in the area were also struck by the gunman’s flurry of bullets, the official said.

“[With] that large crowd right there near Stonewall Memorial, it’s amazing that no one else was hit,” he said.

The male shooter has not yet been caught, and his gun has not been recovered, cops said.

Investigators later learned that another 17-year-old girl – who appeared to be part of the initial teen shooter’s crowd – was slashed in the mayhem, Kenny said.

“We know that she was with that group based on video surveillance and from body-worn camera,” Kenny said. “She suffered a laceration to her upper chest area that punctured her lung. She is currently being treated at Bellevue Hospital and is not likely to die.”

Greenwich Village and specifically the Stonewall Inn, where the 1969 Stonewall Riots effectively marked the start of the country’s gay rights movement, has traditionally been at the heart of the city’s annual Pride celebration.

Mayor Eric Adams said he was briefed on the shooting after the parade in a statement he shared on social media.

“Saddened to learn about the shooting by the Stonewall Inn tonight as Pride celebrations were winding down,” Adams said on X. “During a time when our city should be rejoicing and celebrating members of our diverse LGBTQ+ community, incidents like this are devastating.”

Gov. Kathy Hochul echoed similar sentiments at an unrelated event Monday.

“People deserve to be safe and feel safe,’’ Hochul said.

The shooting occurred several hours after a 23-year-old New Yorker allegedly unleashed bear spray at a massive crowd of Pride revelers inside Washington Square Park, apparently out of fear of being assaulted himself, cops and sources said.

The suspected sprayer, Dominick Sabater, 33, of Harlem was charged Monday with raps including assault, reckless endangerment and unlawful possession of a noxious material, cops said.

The Manhattan man claimed he whipped out the 8.1-ounce can of bear spray because he thought he was about to be jumped or get involved in a fight and used it as a deterrent to keep people away from him, authorities and sources said.

More than 50 people were injured during the chaos — either by the potent chemical spray or the ensuing stampede, according to police.

Additionally, a dozen police officers who were exposed to the spray were taken to Northwell Greenwich Village Hospital for treatment, police said.

Sabater has one previous arrest in the city: a 2021 bust for an apparently unprovoked assault in which he allegedly reached into a car around Union Square in Manhattan and struck a man inside in the right eye with a cellphone, police said.

The men were strangers to each other, cops said.
