Authorities say a Gurnee resident received a random call saying that a school shooting would occur in Grayslake Thursday but the threat has since been deemed not credible.

Grayslake-based Community Consolidated School District 46 Superintendent Dr. Lynn Glickman said in a message to parents that the district was notified by the Grayslake Police Department of a threat late Wednesday evening.

A Gurnee resident received a random and unsubstantiated threat by phone call that a school shooting would take place at a school in Grayslake Thursday, Glickman said.

No specific school was named and the call originated from a spoofed IP address.

Glickman said there was no credible or verifiable threat but out of an abundance of caution an increased police presence would be around schools.

“While the unsubstantiated threat is on schools in Grayslake, we have chosen to share this message with families at all of our schools and will take precautions at all of them as well. Safety is always our highest priority,” Glickman said.

In an updated message, the school district said the police department developed new information Thursday morning showing that the threat “is even less credible, and has nothing to do with Grayslake.”

Glickman said schools will resume business as usual, including having outdoor recess and P.E.

“We know that some of our students may be late to school today, as some families had chosen to keep their children at home, and may now be choosing to bring them to school,” Glickman said.

The district thanked the Grayslake, Round Lake and Round Lake Beach police departments for being present at schools Thursday morning.

The Grayslake Police Department said they provided additional police presence at schools despite the threat being not credible.
