A South Side elementary school was placed on lockdown Thursday morning after CPS officials say a fired teacher threatened the safety of students.
The Schmid Elementary School teacher was let go on Wednesday, and according to police, as he was leaving the building he threatened to come back and "shoot the place up."
School officials asked officers to check everybody going in and out of the school as a precautionary measure Thursday morning.
The fired teacher did not appear at the school, but was taken into custody later at another location. No charges were immediately filed in the case.
The students were back in class Thursday afternoon.
