The CHP said officers arrived to find an "extremely aggressive bear" had entered through an open window and the occupants had locked themselves in other rooms to hide from the animal.
The bear "proceeded to destroy the house looking for food," the CHP said. "The bear charged at officers multiple times until they were able to get it back outside."
Police found the bear was a mother with three cubs waiting in a tree outside.
"Good reminder to all who live up here and all that come to play up here, you are in bear country and it was their home first," the CHP said.
