BELMONT, Calif. (KRON) — A lockdown was issued at Carlmont High School in Belmont Friday afternoon, police said in a tweet. As a precaution, residents were advised to stay out of the area.

That lockdown was later lifted at 3:25 p.m. There was no harm that resulted from the lockdown.

The high school initially locked its doors due to reports of at least one gunshot near the area around 2:15 p.m. Then, Belmont police told Carlmont High School to go into “secure mode,” and the threat was resolved roughly an hour later.

Although Belmont police used the term “lockdown,” the school went into “secure mode,” according to the superintendent. “Secure mode” means for the school to lock its doors out of precaution, but there is no imminent threat.

Carlmont High School is located on the block of Valegra Drive and Alameda de las Pulgas. No other information was released.
