Lakewood High in St. Petersburg was placed on lockdown Monday morning following reports of a weapon on campus, but the threat was later downgraded and the school was placed in lockout status instead.
St. Petersburg Police spokeswoman Sandra Bentil said the police received a report of a weapon at 9:37 a.m. She said police are searching for it. A lockdown was called around 9:45 a.m., meaning students and staff were required to stay at their locations within the school.
Under the lockout, they are allowed to move from class to class but no one is allowed into the school.
Pinellas County Schools spokeswoman Lisa Wolf sent out a message to Lakewood High parents asking them to refrain from traveling to the school as police "(investigate) a safety threat."
A video submitted around 8:30 a.m. to Snapchat, a popular smartphone app, shows a student wielding a handgun, pointing it at the camera with the location tagged as Lakewood High. The subject appears to be a student and lockers can be seen in the background.
It was not immediately known whether the video was related to the lockdown.
No additional details were immediately available. The school, located at 1400 54th Ave S in St. Petersburg, has 1,094 students.
