Lockdown measures continued Friday at St. Anthony's in South Huntington after a bomb threat was found.
Officials say a note was found in a boys' bathroom of the Catholic school on Wednesday.
The note threatened that a bomb was set to go off in the school during the week.
The note read in part, "No one treats me right and because of that, this school is going to go down in pieces."
Police searched the school and deemed it safe.
Bag checks and lockdown procedures went into effect yesterday.
