An animal rights group has said it is in negotiations to place a billboard ad in Dublin showing a human leg on a plate.

People for the Ethical Treatment of Animals (PETA) said the planned campaign comes as gardaí are investigating the discovery of human remains at a recycling plant in Dublin.

In a press release, PETA said that "eating meat is eating a corpse" and urged people to take up a vegan lifestyle.

PETA spokeswoman Yvonne McNulty-Taylor said: "Maybe this tragedy will cause people to think about where their meat comes from every time they sit down to eat."
