A new Banksy has appeared in west London - showing a goat balancing precariously on a tall, thin wall. 

The animal appears to be moments from falling - with rocks and rubble tumbling down from the height. 

Soon after the artwork appeared at Kew Bridge, Banksy confirmed that it was his by sharing a photograph on Instagram. 

The post has prompted lots of speculation online - with many users contemplating the meaning behind the spectacle.

Art teacher, Amber Doffman, 26, spotted the iconic street artist's Instagram post of his new work.

She said she immediately recognised its location and rushed straight out the door to go and find it.

She said: "I saw his post on Instagram 40 seconds after it went up and I immediately recognised where the art was.

"So I got in my car and raced there. I was there 15 minutes after he posted on Instagram - and the paint was still wet."

Amber, who lives in Acton, said she has been writing to Banksy for years - and just a few months ago emailed him asking him to come to west London.

"I emailed him asking him to come to west London and now here he is," the teacher said.

"I'll tell myself I made this happen. I mean, probably not - but it is a huge coincidence.

"I just can't believe he was standing there. It's unbelievable."

Amber added that she believes the artwork is a commentary on the environment.

She said: "I think it's to do with the environment - and how we've ruined it to the point that animals don't know where to go anymore.

"It's also worth noting that that security camera wasn't facing that way before. Banksy has turned it towards the goat.

"It's like it's wanting its attention."

Amber said the occasion was particularly special for her - because he is the reason she took up the career she did.

She said: "He is my idol and the reason I became an art teacher.

"I am beyond inspired by Banksy.

"I hope they cover it with Perspex immediately before someone ruins it - I'm so scared it will get vandalised."
