A 16-year-old innocent bystander was wounded by a stray bullet Monday during a fight outside a Queens high school, police and sources said.

The trouble began when a group of teens jumped a 16-year-old boy during dismissal at the New Dawn Charter High School II in Jamaica, sources said.

“When I heard it I thought it was firecrackers from down the block — sounded like four or five shots,” said eyewitness Tony Augusto, who was coming out of work nearby when the shots rang out.

“By the screaming and people running like that, I’m thinking someone got hit, someone got hurt,” he said. “Unfortunately, it was a girl in this instance. These bullets don’t have names.”

Police are now looking for the shooter.

The incident comes two days after Aamir “Buddy” Griffin, 14, was shot and killed by a stray bullet at a Queens housing project.

Police said the shot that killed Griffin on the basketball court at Baisley Park Houses in South Jamaica was fired from more than 100 yards away.

The girl was rushed to Long Island Jewish Medical Center following the 3:48 p.m. shooting, where she was listed in stable condition.

Police said her injuries were not believed to be life-threatening.
