A 14-year-old who fired a pellet gun at students at a DeKalb County elementary school in April pleaded guilty Wednesday to 10 counts of aggravated assault, district officials said.

The teen, who was not identified because he is a juvenile, shot at 10 Wynbrooke Elementary School students from a position off campus on April 25 as they played outside, authorities said at the time. The school was placed on lockdown.

Nine students were taken to Children’s Healthcare of Atlanta at Egleston while another was picked up by a parent, hospital spokeswoman Ayana Isles said. All of the students were released the same day.

The pellet gun used in the shooting was discovered the next day after DeKalb school police searched the teen’s home, authorities said previously. He was arrested the following week in Durham, North Carolina.

District officials praised the handling of the incident by school administrators and local police.

“The response time of our dedicated law enforcement professionals — both on the scene and pursing all leads — is a testament to the fine individuals working in and around our schools,” DeKalb Superintendent Stephen Green said.

District officials said in a statement that the “adjudicated delinquent” was convicted of all charges, but it remains unclear what his sentence is or if he will serve time at a juvenile detention facility.
