NEW YORK (AP) — Authorities say at least 21 people were shot across New York City over the weekend. Four victims died.

Among those injured were a 10-year-old boy and a 25-year-old man. They were shot Saturday on Brooklyn’s Coney Island and are in stable condition.

Nine people were shot in Brooklyn, five in Manhattan, five in the Bronx, one in Queens and one on Staten Island.

Police are seeking tips from the public as they investigate.

About 600 new officers are graduating from the Police Academy on Monday. They will partner with veteran officers and be sent out to target the most violent, crime-ridden neighborhoods.
