A student reported seeing a firearm in a restroom, prompting the lockdown.
The weapon turned out to be a BB gun, school officials said.
The school later returned to a Code Green and class dismissal was on a normal schedule.
Bringing a weapon of any kind on campus is a serious offense. The student responsible will be disciplined in accordance with WCPSS policy, school officials said in a statement.
Students and parents can report any suspicious activity to a school staff member or to the school district's anonymous tip line: (919) 856-1911.
