CLEVELAND - CMSD officials are investigating a security breach at JFK High School.
According to CMSD's Roseann Canfora, a side door used as the teacher entrance was left unlocked and unwatched Monday morning.
The door is supposed to be manned by staff.
When the door monitor arrived, the person found the door unlocked.
"The door should have been locked. It was not. Now it is and CMSD is investigating," said Canfora.
CMSD also said they reviewed security footage and no students, or anyone other than faculty, entered the building while the door was unlocked.
All students and those not on staff must enter the school through the main entrance, which is monitored by security officials, an X-ray machine and metal detectors.
