Watch: Vegan activists play audio of cow slaughter at Brighton steak restaurant

Vegan activists stormed a steak restaurant in the UK and forced diners to listen to a cow being slaughtered, footage shows.

A group of protesters from animal right's organisation Direct Action Everywhere walked into Touro Steakhouse in Brighton, armed with picket signs and banners.

They stood around tables full of people eating dinner and chanted, "It's not food, it's violence", for several minutes, reports The West Sussex Gazette.

The activists also played a loud audio clip of a cow being slaughtered.

In response diners jeered, laughed and mooed at the protesters, with a group on a stag night even breaking into song to drown them out.

After one activist tried to convince the steak-loving patrons that eating meat is immoral with a speech, the group reportedly made their way back outside to resume chanting.

Police were called but no arrests were made.

A spokesperson for Direct Action Everywhere told The West Sussex Gazette that humans "can no longer ignore the suffering and pain we cause".

"Animal exploitation has become so normalised it goes virtually unnoticed but we are paying attention. People and businesses should not be able to enjoy the product or profit of animal suffering."
