FRESNO, Calif. (KFSN) -- Edison High School went into a brief lockdown for reports of a person with a weapon near the campus.
The lockdown came as Fresno Unified planned to unveil a new peace garden at the school Friday morning.

Officers say a social media post showed a student's face covered with what police think was a weapon. Edison High was then placed on lockdown as a precaution.
A school resource officer saw a person who possibly matched the description of the person in the post.
