NEW YORK (MYFOXNY) - The lockdown of two schools in the Bronx was lifted after police discovered a toy gun.

The NYPD conducted a sweep of the schools Tuesday morning after the principal of P.S. 4 called in a report of a student possibly carrying a gun.

A student told the school aide that he heard another student had a weapon inside the school on Fulton Ave. The student did not actually see a gun, said police.

The building which also houses P.S. 171 was under lockdown for more than an hour while police conducted their search.

They eventually found a toy gun, reported to be a Nerf gun that fires foam "bullets."

Two students from P.S. 171 said they were told to crouch under their desks during the sweep.

A large group of parents lined up outside the school to pick up their children after word spread of the lock-down. Many were frustrated that their children remained inside.

By 10:45 a.m., parents were allowed to enter the school and pick up their children.

On Jan. 15, a lime-green Nerf toy gun also caused an hours-long lock-down at a Long Island school.
