GROVE - Criminal charges are expected to be filed with regard to a bogus bomb threat called into the Grove High School campus, Police Chief Mark Morris said Thursday.
School officials received a telephone call reporting the bomb shortly before 1 p.m. Wednesday.
All four campuses in the district were ordered to implement lockdown procedures, all access roads were blocked, students were moved into secure locations and gas lines were shut off, Morris said.
After a search of the school, no explosives were found and police declared the threat a hoax.
“We have developed some suspects and are following up on the leads,” Morris said.
No arrests have been made, but Morris indicated that suspects include students and adults.
“Charges should be filed in the next few days,” Morris said.
There are specific state and federal statutes dealing with making a bomb threat, he said.
Wednesday's bomb threat hoax cost the city approximately $3,000 in man hours.
“If there has been any explosives found - students would have been evacuated,” Morris said.
Morris explained secondary security issues prompted authorities to lock the school down and move the students to another location.
In some past school shootings, students have been killed when an assailant opens gunfire on students leaving the school, Morris said, citing the Columbine, Colo., school massacre.
During the lockdown, students' cell phones were turned off, Morris said. Authorities were able to search most student's lockers by a master key, while some lockers had to have locks cut.
