Belleville School District 201 Superintendent Jeff Dosier sent a letter to district parents Friday saying a BB gun might have been brought onto the campus of Belleville East High School on Thursday.
"It is our understanding that the student may have brought a BB gun to school on the day in question," Dosier said in the letter.
After being notified by other students, school officials conducted a search of the student, the student's locker and other personal items, but found no weapon.
"We want to emphasize that at no time were students threatened or in harm's way during this incident," Dosier said in the letter. "The school district commends the students involved for doing the right thing."
Belleville Police Department took control of the investigation and found a BB gun following a search of the student's home.
The student's name was not released due to student confidentiality laws. Dosier on Friday said school officials continue to investigate the matter. He said it's too early in the investigation to say if any disciplinary measures will be taken against the student.
However, Dosier said district officials will report the student to the Illinois State Police under a new law that requires schools to report any student who may be dangerous.
"It's one of those thing where we don't even think it's a working BB gun," Dosier said. "Kids for some reason haven't gotten the message -- these kind of toys, weapons or anything that resembles a weapon can't be anywhere near schools."
