An alleged bomb threat written on a bathroom wall prompted a 30-minute soft lockdown at Old Quarry Middle School on Tuesday.
In an email to parents, Old Quarry Principal Bill Caron said the school went on lockdown Tuesday morning after a student reported to a teacher that he saw scratched-out words that looked like "school bomb" in a bathroom.
"When investigated by staff the small words were not readable but may have contained the words the student stated," Caron said.
To ensure student safety, school officials notified the Lemont Police Department implemented a soft lockdown in which students were required to stay in their classrooms while hallways and bathrooms were searched.
Nothing out of the ordinary was found in or around the building, and normal activities resumed about 30 minutes later, Caron said.
"We continue to work with the police department, interview students who may have information, and will keep our parents/guardians, students and staff informed of any further action which may need to be taken," Caron said in the letter.
Officials said the incident was isolated to Old Quarry, and did not affect River Valley or Oakwood schools.
