A special education student was injured after being shot outside of his school in Queens yesterday, police and education officials said. The 16-year-old student had been standing by a city bus stop in front of the Queens Career Development Center shortly after 10:30 a.m. when a fight broke out, police said. A gun was fired, and a bullet hit the student in the collarbone. Two police officers driving by the scene at 142nd Street and Linden Boulevard in Jamaica heard the shot and jumped out of their patrol car to confront the suspects, police said.

A gun battle then broke out between police and the teenagers after one of the suspects turned to fire at a police sergeant. Police officials said the sergeant fired back, but no one was hit by any bullets in the exchange.

The group of teenagers scattered, and one of them dropped a .25 caliber handgun in a nearby driveway, police said.

The injured student was conscious as he was driven to Jamaica Hospital in an ambulance, and he remained there during the afternoon in stable condition, a spokeswoman for the Department of Education, Marge Feinberg, said.

Police said they had arrested one suspect, but they believe he did not fire the gun. They were searching for other possible suspects, and locked down the nearby school building for several hours today. The building houses both the Queens Career Development Center and another alternative high school, the Queens Academy, which serves mostly overage students. Ms. Feinberg said the students were taking Regent’s exams yesterday, and had to take the tests despite the lockdown of their building. The lockdown was lifted by about 1 p.m.

Police said the shooting was under investigation, and they did not yet have a description of the suspect or information about how many shots were fired during the gun battle.
