A VIDEO of a horse taking a poo in Morrisons is circulating the internet. 

At around 9pm yesterday evening, Thursday, a customer caught the bizarre moment on her phone.

The footage shows a man riding a small pony out of Stockton Heath Morrisons before it takes a poo in the foyer. 

It has been widely shared on social media. 

A Morrisons spokesperson said: "A four-legged customer was seen in our Stockton Heath store on its daily carrot shop. While Morrisons usually welcomes everybody, we’re not keen on customers horsing around so we asked it politely to leave."
