The John Silber Early Learning Center, or Shurtleff School, was put on a heavy lockdown Wednesday afternoon after police responded to shots fired on Congress Avenue.
There were no injuries as a result of the incident.
At 1:30 p.m., the ShotSpotter system triggered at 101 Congress Ave. near the school. Police discovered one man in the area who was hiding shortly after the incident. He was found to have a replica firearm on him and was taken into custody. However, later, witnesses said he had not been the shooter, but rather the intended victim.
Chelsea Police are looking for additional suspects.
Police were stationed at the school during the lockdown, and things were soon restored to normal. School was released by 2:30 p.m.
