Nerf-ous Nellies’ school alarm

Jittery officials put a Bronx elementary school into lockdown yesterday after an aide overheard a student say “something about a gun’’ — which turned out to be only a toy Nerf gizmo he had at home.

The school worker heard the 12-year-old boy talking to a classmate about the “gun’’ at PS 4 at 1701 Fulton Ave. in the Morrisania section at 8:15 a.m., cops said.

The worker alerted school officials, and they immediately closed down the campus as heavily armed police swarmed the building.

The boy later told cops he was talking about his Nerf toy, which was at home.

Even though it turned out to be a false alarm, parents rushed to the school, fearing the worst during the two-hour ordeal.

“It’s nerve-racking. There [were] police officers here with assault rifles, and there [were] helicopters flying around,” said Jacklyn Williams, mother of a 9-year-old student.
