Police said five people were shot in a fight as thousands celebrated West Indian American Day in Brooklyn on Monday.

A senior police source on the scene near Eastern Parkway and Franklin Avenue said a gunman stood on a parade barrier on the north side of the Eastern Parkway Service Road and fired into the crowd. A New York Police Department spokesman told NBC New York that the annual parade, one of the world’s largest gatherings of the Caribbean diaspora, did not appear to be the target of the shooting, which left at least two people in critical condition.

Participants in Monday’s parade included senior NYPD officials, Mayor Eric Adams and Governor Kathy Hochul.

The investigation is ongoing, but a suspect has not yet been arrested, NYPD officials said in a press conference near the Brooklyn Museum. Authorities are looking for a gunman in his 20s who was wearing a brown shirt with paint stains and a black bandana.

“This was an intentional act by one person against a group of people. We certainly do not have a shooting or anything like that on Eastern Parkway at this moment,” said NYPD Chief of Patrol John Chell, adding that the parade would continue throughout the night with a heavy police presence.

In Brooklyn, where hundreds of thousands of Caribbean immigrants and their descendants have settled, the parade was first held in the 1960s.
