GREAT MILLS, Md. (AP) — School officials report that there's been a shooting at a Maryland high school, that the 'event is contained' and the campus is on lockdown.
Federal agents from the bureau of Alcohol, Tobacco and Firearms are going to the scene, their agency tweeted.
The St. Mary's County Public Schools said on its website early Tuesday that there was a shooting at Great Mills High School, located in the southern end of the state.
The county sheriff said deputies are on the scene, and that parents or guardians should stay away, going instead to Leonardtown High School to reunite with Great Mills students there.
Maryland Gov. Larry Hogan and Rep. Steny Hoyer tweeted that they're monitoring reports and urged people to follow the instructions of local law enforcement at the scene.
