Carl Court/Getty ImagesALBANY, New York (CNN) - A 17-year-old male was arrested Monday for allegedly posting on Facebook that he would participate in a shooting at an Albany, New York, high school, police said.
The lockdown lasted about an hour, City School District of Albany Superintendent Kaweeda G. Adams said in a statement on the school district website.
School district administrators and security teams worked "through Sunday night" to investigate the Facebook threat, Adams said in a statement.
"The safety of the students, faculty and staff is of paramount importance to the City School District of Albany," Adams said.
The 17-year-old, who police have not named publicly, attends a different school in the same district, according to Smith.
