Update: Lockdown lifted at West Valley College in Saratoga following report of armed intruder

SARATOGA -- A lockdown at West Valley College in Saratoga was lifted Monday afternoon after several hours following a report of an armed intruder on campus. The school said two people had been detained and a replica firearm recovered.

The college sent a tweet alerting of the campus lockdown just after 11 a.m.

Another tweet at 11:32 a.m. said police were checking for a white male seen carrying a long rifle and associated with red Cadillac in Lot 1. 

The school posted the following alert on its website: 

Options RUN if you can safely run OFF CAMPUS - No driving cars. Leave belongings behind. HIDE if you do not know where the threat is or how many suspects are involved, FIGHT if an intruder comes into your hiding place. You will be notified as soon as possible when it is safe.

Campus police told KPIX there was no active shooter situation and officers were looking into whether the object the person was carrying was even a weapon at all.

As of 1:25 p.m., the lockdown was still in place and police were still investigating, the school said on its Facebook page. Classes were canceled for the remainder of the day.

At 1:31 p.m., the Santa Clara County Sheriff's Office tweeted that there was no active threat at this time and the campus was safe.
