A student's text message reporting shots fired at Roxana Senior High School prompted a lockdown at the senior high and junior high schools, according to school officials.
Local responders took action immediately to initiate lockdown procedures at the schools, which are located in the 400 block of North Chaffer.
The student who sent the text message was found, and it was confirmed that there were no shots fired, according to a statement from Roxana Police Chief Will Cunningham.
He said the police department is still investigating the incident and one person of interest was interviewed.
Formal charges may come as early as Wednesday, Cunningham said.
"We are thankful that there was no real threat to students or staff," Debra Kreutztrager, superintendent of Roxana Community Unit School District 1, said in a statement. "However, we do take every action to ensure student safety at all times."
In addition to Roxana, surrounding police agencies responded to the schools including Wood River, South Roxana, Hamel, Hartford, Bethalto, Madison County, Illinois State, Granite City and East Alton.
"With the numerous response teams, they were able to quickly confirm that there were no shots fired and all students and staff were secured," Kreutztrager said in an email statement. "We appreciate the cooperation and patience from our families who worked with responders throughout the situation."
Following the lockdown, students were permitted to return to their regular schedules and were dismissed at the normal time -- 2:40 p.m.
Roxana Senior High School has 580 students, and Roxana Junior High has 419 students, according to the 2013 Illinois School Report Card.
