An officer was conducting a security check when he discovered a group of juveniles. When the officer attempted to contact that group, they fled in the direction of the school. The officer called for helped and they detained three juveniles, one of whom was armed with a loaded handgun. Three others reached the school, and the police cautioned the school to issue a lockdown. A perimeter was set up around the campus and SWAT teams were called in to do a precautionary search. There were no shots fired.

According to Newark Memorial Junior Amy Hoang, most of the students were calm while some were gossiping or trying to gather info on the situation. Former MSJ student Peter Gao said, “When they told us it wasn’t a drill, everybody became more excited and no longer stuck to lockdown procedure. I’m glad everyone was safe.”
