GREAT MILLS, Md. (AP) — The Latest on the shooting at a Maryland high school (all times local):

10:45 a.m.

The principal at the Maryland high school where there was a shooting Tuesday morning told parents last month that the school had investigated threats of a possible shooting and found they were "not substantiated."

Great Mills High School Principal Jake Heibel told parents that school officials interviewed two students in February who were overheard mentioning a school shooting and found that they posed no threat. His letter was posted on the local news site The Bay Net.

But Heibel said the school still increased its security after social media posts about a possible school shooting "circulated quite extensively."

St. Mary's County Sheriff's spokeswoman Cpl. Julie Yingling says three people, including the shooter, were injured in Tuesday's shooting.

FBI agents are on the scene of a shooting at a high school in southern Maryland.

FBI spokesman David Fitz says the agents are there to assist the local sheriff's office and he had no immediate information about injuries or fatalities at Great Mills High School.

Agents from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives have also been sent to the school.

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.

Local and social media first reported a shooting on the campus of Great Mills High School in Great Mills, Maryland. FOX News has confirmed the shots fired. One student reported that one person was dead. Law enforcement sources have not confirmed those details at this point.

The school is on lockdown and is located south of Washington, D.C. and parents have been told not to report to the high school. The St. Mary's County Sheriff says the incident is "contained".

The FBI is on the scene as well as ATF officials from the Baltimore field office. The shooting comes just about a month after the mass shooting at Parkland High School.
