A possible Northern California high school shooting was prevented thanks to a report sent into a tip line created by a nonprofit that aims to prevent gun violence, the organization said.

Sandy Hook Promise said in a statement Monday that the Sequoia Union High School District was able to stop the potential school shooting from taking place after a student reported that a classmate was exhibiting warning signs in their Instagram posts. The student then sent that information to the organization's "Say Something" anonymous reporting tip line.

"This set off a swift chain of events that ultimately saved lives," the Sandy Hook Promise statement said.

According to the report, the alleged suspect posted "detailed threats" on their social media account about carrying out a school shooting within the district, Sandy Hook Promise said. The suspect's posts included pictures of firearms, ammunition and a "mapped-out plan for attacking the school."

After the tip was reported, Sandy Hook Promise notified local police, who then placed two schools on lockdown as a precaution, according to the statement.
