A receptionist at Chapel Hill High School confirmed Tuesday at around 2:45 p.m. that the school was locked down as a precaution Tuesday but that the lockdown was no longer active.

The receptionist couldn’t give further details about why the school was placed on lockdown or when it occurred. She said Assistant Principal Kevin Kay could provide more information, but when forwarded to his extension, he did not answer.
