Great Mills High School in Maryland was on lockdown this morning after a shooting at the school. The event has been contained, a police officer said.
There was no immediate information about any possible injuries or deaths.
A spokesman for the FBI’s Baltimore field office said its agents are on the scene of the incident. Special agents from the ATF’s Baltimore office are en route to the reported shooting, that office tweeted.
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 will then be escorted out of the school, Freese said.
“I’m still a little shaken up,” he said.
Freese said the school had held drills a couple of times for this kind of situation.
“I didn’t really expect for this to happen. I do always feel safe, though, because they always have police at the school,” he said.
According to CNN’s research, there have been 16 confirmed school shootings this year in the United States prior to today.
