WINSTON-SALEM, N.C. (AP) — A planned fight among young people escalated into a mass shooting at a North Carolina park Monday morning that left two people dead, authorities said.

The shooting happened around 10 a.m. at Leinbach Park, which is near Jefferson Middle School, according to Winston-Salem police. Multiple people were injured, with two ultimately succumbing to their wounds, as per a statement by the North Carolina State Bureau of Investigation.

Authorities revealed that two juveniles had arranged to meet at the park for a fight, which led to the discharge of a firearm and the resulting injuries. Assistant Chief Jason Swaim from the Winston-Salem police addressed the media, stating that they have identified numerous individuals connected to the incident but are still determining their exact roles—whether they were suspects, victims, or witnesses.

As a precaution, schools in the vicinity were confirmed to be secure, and parents were offered the opportunity to pick up their children from Jefferson Middle School.

The incident took place in a suburban area northwest of downtown Winston-Salem, a city of approximately 250,000, historically recognized as the base for R.J. Reynolds Tobacco Co.
