Sylvan Hills Middle School was placed on lockdown Monday morning as a result of its administrators reporting to the city police department there was a gunman on the grounds.

No gunman was seen,” said Deb Roush, a spokesman for the Pulaski County Special School District.

Roush someone heard over the school’s two-way radio system used by administrators that there may be a gunman at the school.

The school reported the incident to city police who arrived at the scene and put a perimeter around the building as a search commenced at about 11 a.m., according Sherwood Police Spokesman Richard Harper.

“We searched the school and surrounding area and found no one,” Harper said.

Harper said the police could not verify if what was heard over the school’s two-way radio system was true, but it locked down the school as a precaution.

“The police took measures as if there was an actual threat,” Harper said. “We were there a couple of hours.”

No students were at the school because it was a legal holiday due to President’s Day and Daisy Gatson Bates Day, but 60 school teachers found themselves in the building at the time.

“The teachers were doing their professional development,” Roush said. “The teachers did a great job. They located to the gym and picked up where they left off.”

Roush said PCSSD schools have no experienced any gun-related problems since the December Sandy Hook school massacre in Connecticut.
