LOUISVILLE, Ky. (WDRB) -- LMPD units were called to Central High School early Monday after someone reported hearing a conversation on a TARC bus that referenced a possible shooting at the school today. 

MetroSafe dispatchers did confirm that officers were responding to a "possible unspecified threat" but did not believe the threat was credible. 

Around 10 a.m. JCPS spokeswoman Bonnie Hackbarth released the following statement: 

The internal building sweep of Central High School is complete and security has given the all clear. The school will remain on security level 3 for the remainder of the day, but classes are operating as normal.

There have been more than a dozen threats this school year.
