A Ventura County high school was placed under lockdown as authorities investigated a threatening note found on campus around 8 a.m.

All of the students were evacuated from the campus. School Administration canceled classes for the remainder of the day.

At least 70 deputies and three K-9 units conducted a precautionary sweep of the campus.
