Police say it was around 12:20 p.m. when officers were called out to the Feltonville School of Arts and Sciences, located on the 200 block of East Courtland Street.
The school was placed in lockdown because the students said that they saw a man in the cemetery near the school possibly armed.
The children reported the incident to several adults who then called police.
Police were unable to find the man.
The lockdown was later lifted around 3:30 p.m.
