A Mattituck High School student was grazed in the head by a bullet that went through a window and into the school building Thursday afternoon, officials said.
The female student's injuries were "very minor," and less than an hour later a 28-year-old Mattituck man "was identified as a source of the gunshot" and taken into custody, Southold police said.
Mattituck High staff notified police at 1:53 p.m. that "an unknown projectile was shot through an east side window of the school and did strike an 18-year-old student in the head while seated in a classroom," police said in a news release.
Responding officers recovered a small-caliber round in the classroom, police said.
Administrators locked down the building while police investigated and determined that the 28-year-old man fired the gun, police said.
Police did not immediately release the suspect's identity.
The man lives near the school and was being questioned, Police Chief Carlisle Cochran said. Police are working to secure a search warrant, Cochran said.
James McKenna, superintendent of the Mattituck Cutchogue School District, said "there was an incident outside of school . . . about 15 minutes before dismissal."
"There were a couple of loud noises outside the school," McKenna said. "... I believe there was a custodian outside the school who was weed wacking and another student inside the building at the school store" was hit.
McKenna said he did not know what hit the student.
The student who was hit is a female upperclassmen who McKenna said was inside the school store. He said it appeared something came through the window, possibly through the screen.
The female student was grazed by her head. Her parents came to school and she left with them, McKenna said.
