This shocking footage shows a chimpanzee hysterically banging on the glass window of its cage after visitors provoked it by repeatedly teasing it when it already agitated.

The incident reportedly took place at Shanghai Zoo. Located in China’s biggest city, on Friday, 5th April.

Distressing footage filmed by an unnamed tourist shows the disturbed animal continuously banging on the glass, spinning in circles, clapping its hands, and then banging on the glass again.

Zoogoers who reportedly wanted to have their fun by watching the chimp confined in a small space get agitated over the sound of them tapping the glass.

Surrounded by a group of strangers, it apparently did not take long for the locked-up animal to go berserk.

Chimpanzee Mirrors Two Zoo Visitors’ Actions

The person who shared the video said: “It’s really heartbreaking to watch.”

They added: “I was really scared and felt deeply disturbed. I visited the zoo this morning [FRI]. But I feel like it will take me several days to recover from this experience.”

Staff later responded stating that the chimp, an adult male with a rather large tempter, got worked up due to visitors teasing it.

They reminded that such behaviour is not allowed but due to a large number of tourists that day zoo employees could not manage to regulate everyone.

The chimpanzee’s mood has since stabilised, staff added.
