Linden High School was put on lockdown this morning, following a bomb threat that was made via email. All other schools in the Linden school district went into 'Shelter in Place' mode.

The district received the threat about 7:30 this morning (9/7) and immediately began following its emergency-preparedness protocol, according to this letter from Interim Superintendent Russell Ciesielski.

Argentine police, the FBI, and the Genesee County Sheriff's Department were contacted, and a K-9 unit began conducting a thorough sweep of Linden High School.

At 9:27 am, authorities issued an all-clear, and the district lifted the lockdown on the high school and discontinued the Shelter in Place for all other buildings.
