A man and a woman were killed and five other people were injured in two shootings and two stabbings during J’Ouvert celebrations along the West Indian Day Parade route in Brooklyn early Monday morning, police say. Two more people were injured when a motorcycle they were on was hit by a car.

A man and two women were shot at Empire Boulevard and Flatbush Avenue during the pre-parade festivities in Prospect Heights shortly before 4 a.m.

The 20-something-year-old man, who may have been shot in his chest, died of his injuries, according to police. A 72-year-old woman was shot in her arm and a 66-year-old woman was shot in her arms and hands. The two women were in stable condition at Kings County Hospital Monday morning.

A short time later and just a block away at Empire Boulevard and Washington Avenue, a 22-year-old woman was shot in the head, according to police. She was shot just before 4:15 a.m. and transported to Kings County Hospital, where she was pronounced dead.

4 People Shot on West Indian Day Parade Route

Another person was shot at Eastern Parkway and Nostrand Boulevard around 5:25 a.m. He or she was transported to Kings County Hospital in serious condition.

A 23-year-old woman was also stabbed in the lower back at Ocean Avenue and Empire Boulevard shortly before 4:20 a.m. Police say she refused medical attention.

Another person was stabbed in the neck at Eastern Parkway and Classon Avenue around 5:30 a.m. That person was taken to Methodist Hospital in serious condition.

In addition to the shootings and stabbings, two people were seriously injured when a motorcycle they were on was hit by a car. They were hit by the car around 5:20 a.m. and taken to Kings County Hospital in serious condition.

The West Indian Day parade is a rollicking, colorful celebration of Caribbean culture, music, style and food that draws hundreds of thousands of people each year, but it is also a celebration that has been marred by violence in recent years.

Last year, a former aide to Gov. Cuomo, Carey Gabay, was shot by a stray bullet and killed before the parade. Three men have been charged with murder in his death. Another man was arrested in California this month in connection with the deadly shooting.

Mayor de Blasio promised that there would be “the most extensive security ever” at this year’s J’Ouvert celebration, a year after Gabay was shot and killed at the overnight festival in Brooklyn.

De Blasio and top NYPD officials said twice as many police would be at the pre-dawn festival that draws as many as 250,000 people to Prospect Park before the West Indian Day Parade.

“We’re not going to let a few bad apples what is so important to so many New Yorkers,” de Blasio said.

The NYPD said that 200 light towers and dozens of security cameras will be at this year’s parade in addition to the increased number of officers.

Parade-goers said Monday morning that they were glad the police were keeping an eye on things.

“Safety is a must, we appreciate it,” one woman said. “Every year it’s a big celebration, as you can see, and we welcome the presence of the police.”
