Students, teachers and faculty at Ottawa High School participated Thursday afternoon in a regularly scheduled lockdown drill.

The drill, which took place at about 1 p.m. Thursday, went smoothly, Dr. Ryan Cobbs, principal of Ottawa High School, 1120 S. Ash St., Ottawa, said.

“It’s a drill we go through every year in our practice prevention plan to make sure we are able to do the things we need to do and that teachers understand the process,” Cobbs said, adding that teachers were notified of the drill’s date, but not its exact time. “The drill went very well. ... We didn’t have any issues.”

Jerrod Fredricks, master deputy with the Franklin County Sheriff’s office, said his office provided a canine unit during the drill.

“It’s a routine thing — we do it for all the schools,” Fredricks said of the canine unit searching the school, adding that it didn’t discover any illegal substances in the school.

In April, the sheriff’s office’s canine unit reported it found a small amount of marijuana at OHS during a similar routine sweep at the school. School officials often request a periodic sweep to raise awareness among the students that drugs will not be tolerated in the schools, Fredricks said previously.
