COEUR D’ALENE, Idaho – Police arrested a Lake City High School student after he was suspected of posting threats on social media.

The arrest resolves most of the recent threats made at Lake City High School.

The first incident happened on October 6, and involved a Snapchat with derogatory comments directed toward Lake City High school students. The juvenile suspect involved in that incident was identified and is facing disciplinary action through the school district, but CDA PD said criminal charges were not applicable in that case.

In another incident on October 8, another report was made by a female student that said she had been threatened on social media after refusing to send nude photographs. Detectives are working to figure out who sent those threats, CDA PD said in a release Thursday afternoon.

According to a release from CDA Schools, the suspect posted a threat to a LCHS group chat of about 250 made up of students on Wednesday. On Thursday morning, a student called police to report a posted photo of an LCHS student holding a rifle with a caption referencing a "threat list."

On Thursday morning, the LCHS Principal said that a preliminary investigation has led officials to believe the threats are coming from a student. By Thursday afternoon, police had identified and arrested a student.

"[The student] will face school disciplinary consequences up to possible expulsion," CDA Schools wrote in a release.

Coeur d'Alene Police said in a release that juvenile male will face four misdemeanor counts of using the telephone to terrify, threaten or harass.

Wednesday night's alleged threat prompted the school district and law enforcement to enact additional security measures at the high school through Friday.

Scott Maben with the Coeur d’Alene School District confirmed multiple officers will be in and around campus, and administrators will be visible throughout the school. Doors will remain locked and everyone will be required to enter through the secured and manned front doors. Morning bus students will continue to enter through the manned bus loop doors.

The district is taking additional precautions involving cell phone use. Maben said LCHS students will not be allowed to use personal electronic communication devices, including cell phones, during school hours effective immediately and until further notice. Students in violation of the policy will have their devices confiscated. The device will be held by the administration until a parent or guardian retrieves it, and students could face consequences in the form of detention or night class.

“We are seeing highly irresponsible and inappropriate behavior on social media used by many students, and the disruptive effect some of these posts are having on school operations cannot continue. This needs to stop now, and we need your help to make that happen,” Maben wrote in a release to parents.

School administrators encourage parents to talk to their children about their social media use and communication with peers.

The Lake City High School administration had offered a $800 reward for information that lead to the identification of the individual or individuals involved in these social media postings.

Maben confirmed the Coeur d’Alene Police Department worked with the FBI to identify the source of the reported social media threats against students.
