Shooting was reported at a high school on Tuesday in the US state of Maryland, according to authorities.
"The Sheriff's office is on the scene," the school district said, adding that the incident had been contained.
Jonathan Freese, a student at Great Mills, told CNN he was in lockdown in his math class. Police were going through classrooms to clear the school and students would then be escorted out of the school.
"I'm still a little shaken up," the student said.
