Animal rights activists say they have taken three lambs from the King’s Sandringham Estate in Norfolk.
Imagery released by Animal Rising shows three women, in pink Animal Rising t-shirts, walking through a field of sheep and loading the lambs into the back of a vehicle.
Animal Rising said that the woman took the three lambs from Appleton Farm at around 8pm on Wednesday.
The group said that the lambs would have been sent for slaughter.
Animal Rising said that the women handed themselves into the police in Windsor, Berkshire at 8am on Thursday, with banners saying: “I rescued the King’s sheep”; and: “This is how we love animals”.
The group said on its website that the incident “marks the first” of its “high-profile ‘open rescue’ this summer”.
Sarah Foy, 23, one of the women involved, said: “Like anyone, animals want to live out their lives safely and without being used or exploited.
“Sadly that is not the case here at Sandringham, or anywhere they are used in our food system.
“That is exactly why we rescued three sheep today – three beautiful lambs who will now live their lives to their fullest.
“We urgently need a national conversation about our relationship with other animals and nature.”
The Sandringham Estate, Norfolk Police and Thames Valley Police have been approached for comment.
