Tahoe Valley Elementary School was on lockdown the afternoon of Feb. 28.

Lake Tahoe Unified School District officials called it a “false alarm.”

“It was a planned drill started at LTCC in which Tahoe Valley was inadvertently called as part of the LTCC automated phone tree. After the drill, Tahoe Valley’s phone number was removed from LTCC’s automated phone tree,” police Lt. David Stevenson told Lake Tahoe News.
