Kennedy-King College went on lockdown this evening after a report of a man with a gun at the Englewood neighborhood school on the South Side, authorities said.

About 4:50 p.m. authorities received an anonymous call of a man with a gun at the college, at 6301 S. Halsted St., according to police News Affairs Officer VeeJay Zala.

Police went to the scene but the call was unfounded, according to Zala.

City colleges spokeswoman Katherine Hayes called the incident an “unsubstantiated threat.’’

The scare put the school on lockdown for a "brief period,'' Hayes said.

The school's night classes were canceled after officials at the school received unsubstantiated reports of a person with a weapon headed toward the campus, according to a voice mail sent to college administrators at about 5:25 p.m.

CPD squads were on the scene investigating the threat, according to the voice mail.

As of 7:15 p.m., the school was opened and classes are scheduled for Wednesday.
