Wake Prep was closed Thursday and held remote learning while police conducted an investigation into a threat that surfaced Wednesday.
Though law enforcement will continue to investigate, the school said Thursday night that there was "no known threat to any staff or students at this time."
"As fact-gathering in this investigation continues, we ask for your continued partnership and cooperation," the school said in a message to parents and others Thursday night.
The school asked people not to post about the situation on social media, saying it wanted to avoid spreading "misinformation" and causing "unnecessary concern within our community."
There will be an increased police presence on campus Friday, school officials said.
