SPRINGFIELD, Ill. (WCIA) — Springfield Police are investigating after they said they received a false a report of a shooting inside Springfield High School.

Official said dispatch received a call around 1:15 p.m. saying a shooting had occurred inside the school. When called, the School Safety Officer said there had not been a shooting there. Out of caution, officers went to Lanphier and Southeast High Schools as well, but found no issues at either school. The schools were placed on a soft lockdown as a result.

After investigating, officials said they determined several similar calls had been made across the United States falsely reporting a school shooting to authorities.

The Criminal Investigations Division is looking into where the phone call came from to figure out who made the call.
