A minor was taken into custody following a threat made against Plainfield Central High School on social media late Wednesday night, police said.
Plainfield Community Consolidated School District 202 said the threat was posted by a current student but was deemed not credible by area authorities.
“That student will not be in school and appropriate disciplinary action will be taken,” the district wrote on Facebook.
The school was first made aware of the threat around 9:30 p.m. Wednesday and contacted police around 3 a.m. Thursday, according to district spokesman Tom Hernandez.
Police said officers investigated throughout the night and took someone into custody.
“Further investigation shows there were no steps taken to follow through on this threat,” the department said Thursday morning.
An increased police presence was expected at the high school Thursday morning.
“Again, we apologize for the inconvenience and thank you for your understanding and support,” the district’s message read.
