Animal Rebellion targeted a Leeds Marks & Spencer store as they sat in the supermarket's meat aisle on Good Friday.
Police were said to have been called as the group occupied the aisle at the store on Briggate, city centre for around two hours on Friday, April 7. Members of the group - known for previously blocking the entrance to a factory that makes McDonald's burgers and storming Harrods and another store in London, taking cartons and milk and emptying them - held up mock Mail on Sunday front papers.
The papers featured headlines including: "Nation of Animal Lovers Eat Baby Sheep in Odd Annual Easter Ritual."
