Parent John Obin says his son, a freshman at the South Florida high school where the shooting erupted, says his child was in class when he heard several shots.

A shooting at a Florida high school Wednesday sent students rushing out into the streets as SWAT team members swarmed in and locked down the building, and police warned the shooter was still at large. Ambulances converged on the scene as emergency workers appeared to be treating possibly wounded people on the sidewalks.

Television footage showed police in olive fatigues, with weapons drawn, entering the Marjory Stoneman Douglas High School, then dozens of children frantically running and walking quickly out. A police officer waved the students on, urging them to quickly evacuate the school.

Some students exited the building in single-file rows with hands raised overhead to show they carried no weapons. Others held onto other students as they made their way out past helmeted police in camouflage with weapons drawn.

Emergency medical personnel pulled stretchers from the backs of ambulances as police cars surrounded the parking lot. At least one person was seen being wheeled to the ambulance on a gurney. It wasn’t immediately clear how many people were wounded.

Coral Springs Police said on their Twitter account Wednesday that the school was locked down and that students and teachers inside should remain barricaded until police reach them.

The Broward County Sheriff’s Office tweeted that the shooter was still at large even as the evacuation was underway.
