School district officials announced that Northport Middle School will be closed for the rest of the school year amid concerns from parents and students about a foul smell inside the building.

Students will be relocated to Northport High School, East Northport Middle School, Norwood Elementary School and Bellerose Avenue Elementary School. Parents argued that the smell was making their children sick, and staged "sick out" protests.

Officials authorized the hiring of an environmental firm to investigate the source of the stench at a recent school board meeting.
