A wild bear in California has broken into a zoo and paid an unexpected visit to the bear enclosure.
In a Facebook post, the Sequoia Park Zoo in Eureka in the northern part of the state said its staff were conducting a routine inspection of part of the complex when they spotted a wild American black bear leaning on a gate and looking in at three captive black bears in their enclosure.
