Evanston Township High School is under lockdown after an anonymous male phoned in a gun threat to the school.
A note on the school website says students will be required to stay inside the building until the situation is sorted and all outside visitors will be barred from entering.
"We have received an anonymous phone call from a person outside the building who claims to have a gun," the statement reads. "We know that schools do periodically receive anonymous threats, such as bomb threats, and those threats are usually not credible."
School officials told NBC that they recieved the call at about 8:30 a.m. The unidentified male said that he had just broken up with his girlfriend and he was "coming to shoot everyone."
There is a heightened police presence at the school and the increased number of cops will stay there for the remainder of the week.
"Please do not come to ETHS today or ask that your student be dismissed from school today. We have secured the school and we will keep it secure all day. There will also be a huge police presence today when school is dismissed," the school's website statement concludes.
