"Nerf toy causes lockdown at Long Island school"
A lime-green Nerf toy gun caused an hours-long lock-down at a Long Island school on Tuesday.
A 911 caller told Nassau County Police she saw a suspicious teen at about 7:38 a.m. Tuesday wearing a black jacket and carrying a black backpack at Elmont Memorial high School in Elmont.
The caller said he was also carrying a lime green gun.
A SWAT team searched the school room by room. Parents were allowed to pick up their children early Tuesday afternoon. . . .
