SNEAKY activists ambushed a chicken farm after being invited in to look around.
The underhand group suddenly pulled out cameras in front of shocked staff and began filming.
Members of the Chicago Animal Save group posed as ordinary members of the public to attend a guided tour of the Pollos Vivos chicken farm in Chicago.
Some activists locked arms in front of the cages and put red roses in them before police arrived and ordered them to leave.
But they still posted the images on their Facebook page.
Pollos Vivos employee Sam Abed said: “They said they want us to close the chicken farm.
“It’s not going to happen.”
One of the activists said: “We are determined to change the direction of our food system for the benefit of everyone — animals and humans alike.”
Activists from the Chicago Animal Save group have been blocking slaughterhouse trucks and holding vigils for animals since October 2016.
