LEE COUNTY, Fla. (WINK) — Riverdale High School has returned to normal operations after an incident on campus, according to school officials.

The school was placed on secure status Monday afternoon, leading concerned parents to flood nearby neighborhoods. A secure status means entrances and exits are locked while learning continues inside. All students are safe, according to an email form school officials. 

The Lee County Sheriff’s Office said there was an isolated incident, but did not provide more information. Multiple students told WINK News they heard a lunchroom altercation escalated. 

Riverdale High School Junior Eliot Schade said he saw deputies use a dog and drone to search for something near the JROTC tower on campus. 

“You’re hearing everything from the students, not getting much from the school,” Schade said. “So it’s like just a whole lot of speculation.”

Deputies remained in the area hours after secure status was lifted. The Sheriff’s Office deployed multiple dogs and a drone just south of the high school, off Buckingham Road, around 6:00 p.m.

WINK News Reporter Hunter Walterman approached the deputies and asked if it was connected to the incident at Riverdale. A deputy said he could not disclose that information. 

WINK News has repeatedly reached out the Sheriff’s Office for more information, including whether a suspect is in custody.

Riverdale High School Junior Kayce Alvarez said students were kept in secure status for about half-an-hour. Her teacher closed the blinds as sirens get closer to campus. 

“Everybody had to call their parents, let them know what was happening,” Alvarez said. “It’s just insane.”

Daijon Campbell recently graduated from Riverdale. He immediately reached out to his younger brother, Caleb, a junior, after he heard something happened.

“I haven’t been out of school too long, but I know when it comes to code red, code red is very serious,” Campbell said.

Campbell navigated a chaotic pick-up line, as cars blocked an intersection across the street from campus. 

“I’m just praying that justice is served, you know, and whatever needs to be handled is handled,” Campbell said.
