Police said the student made the threat shortly after arriving at school Thursday morning.
He faces a felony charge and is lodged at the Ottawa County Juvenile Detention Center. The boy's name will not be released because of his age, police said.
Authorities say the suspect may be involved in other threats using a telecommunication device.
Students were evacuated from the school Thursday morning after officials were alerted to the threat. West Ottawa Public Schools officials notified 911 at about 7:40 a.m. after receiving information about a possible explosive device at the high school’s south building, said Capt. Mark Bennett of the Ottawa County Sheriff’s Department.
Students were sent to other buildings and the high school was put on lockdown.
Police did a complete sweep of the building and “no harmful device or suspicious packages were found,” Bennett said. No one was hurt during the incident, he said.
The Michigan State Police bomb squad and K-9 units assisted at the scene.
