Officials say a report of a gunman at a Chester school Tuesday appeared to be unfounded.

There was a massive police presence at Chester Free Academy around 1 p.m. after police responded to a report from a student about a gunman inside the school.

Police say they searched the school and found no evidence of the gunman.

They say a special-needs student at Chester Free Academy may have gotten scared and made the report just minutes before a scheduled active-shooter drill.

Police say they don't believe it was a hoax, but that it was unclear whether or not the student got scared.

"The student in the past has had issues with the drill. Usually they're done blind, but because of his past issues, he was given a heads up," said Chester Police Chief Dan Doellinger.

Authorities took no chances and placed the school on lockdown as a safety precaution with a massive, multiple-agency police response.

The lockdown was later lifted.

Police say no one was hurt during the incident and that all the students were safe.

Classes at the school will resume as scheduled Wednesday morning.
