A 16-year-old from Salem has been arrested on firearm charges after the FBI on Thursday flagged a threat to carry out a shooting at West Salem High School.Around 9:30 a.m. on Thursday, June 4, the FBI alerted the Salem Police Department that the teenager had been researching school shootings, access ing materials related to firearm manufacturing and was “displaying concerning behaviors,” according to a statement from police spokesman Sgt. Jon Hardy. The discovery came hours before West Salem’s evening graduation ceremony.Investigators established the teen wasn’t at the high school and that afternoon, detectives surrounded a Southeast McGilchrist Street home. The teenager, who had been in an attached shed, surrendered without incident, according to police. The boy’s connection to the McGilchrist Street property couldn’t be readily established as authorities were releasing little information about the threat or the investigation. The teenager is being held in the Yamhill County Juvenile Detention Center in McMinnville for state charges relating to manufacturing a firearm. The criminal charges will be prosecuted by the Polk County District Attorney’s Office. Detectives worked with the Salem-Keizer School District to “ensure the safety of students and staff,” the release said. Representatives for the school district could not be immediately reached for comment Thursday afternoon about what precautions were taken at the school, such as a lockdown. Aaron Felton, Polk County district attorney, declined to detail the charges the teen is facing, and said the ongoing investigation could change the number and types of charges filed. Felton said he was alerted to the situation Thursday afternoon. “This was isolated to one individual and there is not an ongoing threat to West Salem … or the community,” he said. He also said he doesn’t want people feeling anxious or concerned about attending West Salem High School tonight for graduation, which was scheduled for 6:30 p.m., according to the school district’s website.  Hardy said that the incident was resolved through collaboration among law enforcement, school officials and community partners.  “Their coordinated efforts enabled rapid information sharing and ensured there was no imminent threat to schools or the community. Based on the information gathered, there is no ongoing threat related to this incident,” Hardy said.  The police department worked with the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives.
