A second San Diego school was placed on lock down Thursday, just a few miles down the street from the first.
At about 2:56 p.m., a secretary from Canyon Crest Academy called 911, reporting a message had been sent out via social media that a person was "on the way with three guns."
Students who saw the message told NBC 7 it was posted to Yik Yak, an app that allows users to post anonymously to a message board seen by those within a 1 1/2-mile radius.
School authorities decided to lock down the academy, which is located at 5951 E. Village Center Loop in Carmel Valley.
"It kinda freaked me out a little bit," said sophomore Madison Klaire. "I just thought, like, 'Oh, I hope everything is OK.'"
She and fellow student Cameron Colleran hid underneath their desks in a dark classroom for 45 minutes, waiting for police to give them the all clear.
CCA began releasing students at 3:37 p.m.

Thursday morning, Torrey Pines High School was locked down after another threat through Yik Yak. It's unclear at this point if the two messages were posted by the same person.
Klaire said she used Yik Yak, but now she's having second thoughts.
"Yeah, I liked the app, but now it's weird. I don't want to go on it anymore," she said.
The situations on both campuses prompted nearby Cathedral Catholic High School to close down for the rest of the day.
School officials posted on Facebook that all athletic events and after-school meetings have been canceled, though they say there is no immediate threat to students, faculty or staff there.
Canyon Crest Academy is about three miles from TPHS down Del Mar Heights Road. It has about 1,880 students, grades 9 through 12, that come in from Carmel Valley, Encinitas, Solana Beach, Del Mar, Rancho Santa Fe and La Costa, according to its website.
