A stray bullet hit a 5-year-old child in The Bronx last night as a gunman shot a deli owner in the leg and grazed a woman bystander, cops said.

In the 8:15 p.m. attack on Grand Avenue, the boy was hit in the ankle, eyewitnesses said. The shot woman was not the child’s mother.

Mathew Jimenez, 17, said the boy “hit the floor.”

Witnesses on the street reported hearing five to six shots. “It sounded like fireworks,” said Paulettey Guzman, 22.

Police said the child and man are in stable condition at St. Barnabas Hospital. The woman did not require treatment.
