Law enforcement officers in the US state of Georgia responded on Wednesday to a shooting at a high school and where four people had been killed.
In addition to the four victims, nine people were injured in the shooting at Apalachee High School in Winder, Georgia, MSNBC reported, citing unnamed officers briefed on the incident.
The suspect, a 14-year-old boy, was in custody, the Barrow County Sheriff's Office said in a statement.
The incident appeared to be under control and students were being released at midday, a Barrow County Schools spokesperson said.
"At approximately 10:23 am, officers from multiple law enforcement agencies and Fire/EMS personnel were dispatched to the high school in reference to a reported active shooting," the Sheriff's Office added.
The FBI field office in Atlanta dispatched agents to the high school to support local law enforcement, said Jenna Sellitto, a spokeswoman for the office.
