NEW YORK (AP) — A 7-month-old baby in a stroller was killed by a stray bullet Wednesday afternoon when a man on a moped shot at a group of people on a Brooklyn sidewalk, authorities said.

The shooting was believed to be gang-related and the child an unintended victim, police said.

“There are no words that can mend the heartbreak this family is feeling right now,” Mayor Zohran Mamdani told reporters in a briefing near the spot where the shooting happened. “A life that had barely begun was taken in an instant.”

The shooting unfolded around 1:20 p.m. after two men sped down a street on a moped and the man on the back of the vehicle fired at least two shots at a street corner where several adults and children were gathered. No other injuries from the shooting were reported by police.

The moped sped off, but crashed into an oncoming car two blocks away, Police Commissioner Jessica Tisch said. The impact threw both men off the vehicle so hard that the moped’s passenger lost both his shoes, she said.
