Knoxville (WVLT) -- New details on a lockdown at Powell High School.
Deputies responded to the school a little after 3:30 p.m. after a 9-1-1 caller reported a gun on the campus.
Several Knox County Sheriffs’ Department officers and the helicopter
were on scene within minutes, and at least six cars and the chopper remain there as of 5:30 p.m.
Knox County Sheriff's Department spokesperson Martha Dooley says there were about 30 students still inside the building when it was put on lockdown.
Both Dooley and Knox Schools spokesperson Russ Oaks say all students were out of the school by 4:30 p.m.
But, a source tells VolunteerTV.com a different story.
The source says at 3:30 p.m., teachers were notified over the loudspeaker that the school was placed on lockdown.
Moments later our source tells VolunteerTV.com that teachers were told to barricade themselves and their students in their classrooms.
Eventually, according to our source, students were led to the school locker room where they were searched by sheriff's deputies and then allowed to leave in small groups.
Our source says there are still students left inside the school.
Knox County Schools spokesperson Russ Oaks says today was a test day so as students finished exams they were allowed to leave.
As a result, many had already left when the 9-1-1 call came in.
Another parent on scene tells VolunteerTV.com, her son was just released from the school locker room around 5 p.m.
He is fine.
The outer doors of the school are locked as sheriff's deputies with at least one police dog continue to search the school.
Dooley says no gun has been found.
