Peoria Public Schools went under lock-down Friday after students reported seeing a gun.
The lock-down included all four Peoria Public high schools, but there's still some confusion about the scenario.
The lock-down was put in place after students told school officials they saw a gun somewhere at the Woodruff campus.
Superintendent Sharon Kherat said the student that initially reported the incident doesn't even attend Woodruff.
Richwoods Student Patrick Ferguson said it all happened rather quickly.
Ferguson said officials got on the intercom and said it was "code red."
Superintendent Sharon Desmoulin-Kherat said the measure was a safety precaution.
"We're always going to be professional and do what it takes to ensure that the environment is very safe," said Kherat.
Kerat told 25 News Friday afternoon a search of the schools failed to turn up any weapons.
The lock-down started just before 1:30 P.M. Friday and lasted until approximately 2:15.
Students were released at their regular time.
The Peoria Police Department assisted with the investigation.
